The Importance and Role of Biostatistics in Clinical Research

 “A substantive, thorough, sophisticated literature review is a precondition for doing substantive, thorough, sophisticated research”. Boote and Baile 2005

Authors of manuscripts treat writing a literature review as a routine work or a mere formality. But a seasoned one knows the purpose and importance of a well-written literature review.  Since it is one of the basic needs for researches at any level, they have to be done vigilantly. Only then the reader will know that the basics of research have not been neglected.

The aim of any literature review is to summarize and synthesize the arguments and ideas of existing knowledge in a particular field without adding any new contributions.   Being built on existing knowledge they help the researcher to even turn the wheels of the topic of research.  It is possible only with profound knowledge of what is wrong in the existing findings in detail to overpower them.  For other researches, the literature review gives the direction to be headed for its success. 

The common perception of literature review and reality:

As per the common belief, literature reviews are only a summary of the sources related to the research. And many authors of scientific manuscripts believe that they are only surveys of what are the researches are done on the chosen topic.  But on the contrary, it uses published information from pertinent and relevant sources like

• Scholarly books
• Scientific papers
• Latest studies in the field
• Established school of thoughts
• Relevant articles from renowned scientific journals

and many more for a field of study or theory or a particular problem to do the following:

• Summarize into a brief account of all information
• Synthesize the information by restructuring and reorganizing
• Critical evaluation of a concept or a school of thought or ideas
• Familiarize the authors to the extent of knowledge in the particular field
• Encapsulate
• Compare & contrast

By doing the above on the relevant information, it provides the reader of the scientific manuscript with the following for a better understanding of it:

• It establishes the authors’  in-depth understanding and knowledge of their field subject
• It gives the background of the research
• Portrays the scientific manuscript plan of examining the research result
• Illuminates on how the knowledge has changed within the field
• Highlights what has already been done in a particular field
• Information of the generally accepted facts, emerging and current state of the topic of research
• Identifies the research gap that is still unexplored or under-researched fields
• Demonstrates how the research fits within a larger field of study
• Provides an overview of the sources explored during the research of a particular topic

Importance of literature review in research:

The importance of literature review in scientific manuscripts can be condensed into an analytical feature to enable the multifold reach of its significance.  It adds value to the legitimacy of the research in many ways:

• Provides the interpretation of existing literature in light of updated developments in the field to help in establishing the consistency in knowledge and relevancy of existing materials
• It helps in calculating the impact of the latest information in the field by mapping their progress of knowledge.
• It brings out the dialects of contradictions between various thoughts within the field to establish facts
• The research gaps scrutinized initially are further explored to establish the latest facts of theories to add value to the field
• Indicates the current research place in the schema of a particular field
• Provides information for relevancy and coherency to check the research
• Apart from elucidating the continuance of knowledge, it also points out areas that require further investigation and thus aid as a starting point of any future research
• Justifies the research and sets up the research question
• Sets up a theoretical framework comprising the concepts and theories of the research upon which its success can be judged
• Helps to adopt a more appropriate methodology for the research by examining the strengths and weaknesses of existing research in the same field
• Increases the significance of the results by comparing it with the existing literature
• Provides a point of reference by writing the findings in the scientific manuscript
• Helps to get the due credit from the audience for having done the fact-finding and fact-checking mission in the scientific manuscripts
• The more the reference of relevant sources of it could increase more of its trustworthiness with the readers
• Helps to prevent plagiarism by tailoring and uniquely tweaking the scientific manuscript not to repeat other’s original idea
• By preventing plagiarism , it saves the scientific manuscript from rejection and thus also saves a lot of time and money
• Helps to evaluate, condense and synthesize gist in the author’s own words to sharpen the research focus
• Helps to compare and contrast to  show the originality and uniqueness of the research than that of the existing other researches

What is Literature Review?

A literature review is a critical and comprehensive analysis of existing research, studies, articles, books, and other relevant sources on a specific topic or subject. It serves as a foundational step in the research process, helping researchers understand the current state of knowledge, identify gaps in the literature, and establish a context for their own study.

In most research reports or research papers, you will see that literature review is an essential element and it forms the basis for advancing knowledge, facilitates theory development, discovers new research areas and closes old ones. When researchers want to understand the management dilemma, they study various books, articles and all other available sources.

In the research reports, the researchers present a summary of their search, study and evaluation of the literature that is already available related to the research topic. When the researcher presents a summary of their study of present literature in addition to their analysis of how this literature is related to or essential for the current research report; then, this process is known as literature review.

For example, in a research paper titled ‘Attrition Analysis in a Leading Sales Organisation in India’, authored by Mamta Mohapatra (International Management Institute, New Delhi, India), Amisha Gupta (Birlasoft, New Delhi, India) and Nikita Lamba (Genpact, New Delhi, India), literature review is presented as follows:

Organisations and researchers usually conduct literature review in order to establish how their own research fits within the context of existing literature.

Apart from these, some other objectives of carrying out literature review are:

• Develop an understanding of how each source of literature helps in understanding the research problem
• Examine the interrelationships among different variables
• Find out ways to interpret earlier similar researches on the topic under study
• Rectify the conflicts that exist among previously conducted studies
• Get an idea regarding the required sample size
• Get an estimate of how much variance is there in the variables of interest
• Understand the type of relationship that exists among variables
• Determine the research method that can be used in the research

Importance of a Literature Review

There are various reasons for carrying out literature review. Majorly, literature review helps in:

• Assessing the current state and level of research on a given topic
• Identifying experts related to particular research
• Identifying questions that need further research and exploration
• Identifying what methodologies have been used in the related past studies and what methodology should be used in current research
• Justifying a proposed research methodology
• Indicating the originality and relevance of the given research problem
• Demonstrating the preparedness of a researcher to complete the research

Functions of a Literature Review

Some of the major functions of literature review are:

• Establishing a context for the research
• Demonstrating that the researcher has actually read related literature extensively and is aware of most theory and methodology related to the given research topic
• Providing a shape for the research under consideration
• Establishing a connection between what the researcher is proposing and what he has already read
• Demonstrating how the findings of researcher can be integrated with the already existing research findings.
• Revealing the differences or areas of gap between present and earlier research findings
• Improving researcher’s research methodology
• Expanding researcher’s knowledge base
• Ensuring that the researcher is carrying out new research that has not been carried out earlier

Process of a Literature Review

The second step in the research process is to carry out the review of already existing literature. Before engaging in literature review, the researcher must be clear as to what is the area and topic of research. There are four steps involved in the literature review process as shown in Figure:

Search the Existing Literature in Your Field of Interest

In the literature review process, the first step is to find out what research has already been done in the area that the researcher has chosen. This step involves preparing a list or bibliography of existing sources of relevant literature such as books, journals, abstracts of articles on your research topic, citation indices and digital libraries.

Review the Literature Obtained

After the researcher has identified related literature including journals, books, research papers, etc.; the next step is to study, evaluate and analyse the literature critically. This study of literature helps a researcher identify themes and issues related to the research topic.

An evaluation of literature helps in:

• Identifying the different theories and their criticism
• Identifying different methodologies used in different studies including their sample size, data used, measurement methods
• Assessing if the researcher’s theory is confirmed beyond doubt
• Preparing a list of different opinions of different researchers and researcher should also add his/her opinion about the validity of these different opinions

Develop a Theoretical Framework

Since carrying out literature review is a time-consuming activity but the researcher has to do it within a limited time. In order to do so, the researcher usually establishes a boundary and parameters for the research work. Also, the researcher must sort information obtained from all the sources of literature. For a researcher, the theoretical framework acts as a base on which he can further or extend his research. At times, the researchers may modify their research framework after analysing the available literature.

Write the Literature Review

The last step in literature review is to make a summary of all the literature that the researcher has studied and reviewed. Usually, writing a literature review starts with a write-up on the main theme of research followed by the important ideas on which the research would focus. After this, the all the major themes and sub-themes to be discussed are organised and related. This will help the researcher in structuring the literature review. The researcher should also identify and describe the theories and studies that are relevant for the study under consideration. The researcher should then list and describe all the gaps that are present in the current body of knowledge. In addition, the researcher may also explain the recent advances and trends in the given research field. To conclude, the researcher should compare and evaluate his findings on the basis of research assumptions, related research theories, hypotheses, applied research designs, variables selected and potential future work speculated by the researchers. Finally, the researcher must acknowledge, cite and quote all the sources that he/she has used in his research. One specific characteristic of literature review is that the researcher must ensure that he gives due credit to all people who have contributed in the research work.

How to Write a Literature Review

While writing the literature review, the researcher must adopt or adhere to certain strategies as follows:

• Establish a focus around the central theme and ideas of the research
• Describe what a reader can expect from the given research study
• Organise the literature research to include basic elements such as introduction, body and conclusions

Types of Sources for Review

A researcher usually uses secondary data for literature review. Some of the major and widely used sources for literature reviews include articles in professional journals, statistical data from government websites and website material from professional organisations.

Apart from the previously mentioned sources, certain other sources of data can also be used by researchers that provide them first-hand information that is important for the study. These sources include reports, theses, emails, letters, conference proceedings, company reports, autobiographies, official reports, research articles, etc.

Apart from these, the researcher may also refer to other such as review articles, academic journals, books, newspapers, documentaries, encyclopaedias, dictionaries, bibliographies and citation indexes.

What is the importance of literature review in research, when and how to conduct a literature review, key takeaways.

Literature review sometimes also referred to as literature survey is a process of extensively reading and understanding the literature and the prior works there are within a particular field. Literature here simply refers to previously published scholarly articles which could include- peer reviewed conferences, journal articles, book chapters and so on. While they are not only an academic requirement but essential when planning a research project in general, in this article, we will purely focus on the academic context.

The purpose of literature review in academic or scientific research is very crucial and often remains unclear to an early stage researcher. So, let us at what you can achieve as a part of conducting the literature review for scientific research:

• Context : For any research proposal , it is crucial to provide context to put the research into perspective and establish the significance of the research.
• Competitors : Conducting a thorough literature survey will help you identify who are the scholars (aka competitors) who are actively contributing to your field. This will help you plan your own research well and establish a moat to prevent others from beating you to the punch. In fact, not only competitors, some of these people might go on to become your collaborators down the line if they can bring in complementary expertise.
• Framework : Literature review will help you identify the research frameworks that your peers have already used in the past so you can use this as an evidence and build on top of it.
• Research Questions : The quality of a research question can in turn make or break your research progress. In order to come up with good quality research questions of your own, you would first need to interpret what are the questions your peers are trying to answer. While this is not always mentioned explicitly, but as a part of the literature review, you would be able to carve this information out as your read the prior works.
• Prior works : As the name suggests, prior works are the existing contributions made by your peers prior to you jumping into the field. The term “research” itself can be broken down into “re” + “search” meaning you are searching for what is already known and trying to find a new angle of approach for novel contributions. Literature survey will help you collect all such information to prevent you from re-inventing the wheel.
• Opportunities : As you spend more and more time surveying the literature and understanding what has already been done, you are also understanding what is not being done. With time, you will have your own Eureka moment (often at times when you least expect it), wherein you will uncover research opportunities all thanks to an extensive literature survey.
• Evidence:  At some point in your own research, you would need evidence to support your finding and to prove that they are good enough to warrant a new publication. Your literature review database would come in very handy for this too to help you establish how your results compare to existing state of art.
• Resources : If you are just starting out a project, you may not necessarily know all the resources that you would need to carry out the research. Low and behold, some of your peers might have already gone through this stage already and in their published articles would have documented all such resources- datasets, devices, software, facilities etc. So, you do not need to scratch your head but just put the pieces together.
• Efficiency:  Efficiency is often overlooked and ignored as an outcome of a well structure literature review in research writing. The thing is that, as an early stage researcher, you will be easily distracted as you read more- almost everything that passes by you will sound and feel interesting. This is somewhat similar to what happens when you hop on to YouTube or start watching a series on Netflix. But, a well structured literature review database will actually help you keep such distractions in check and make a decision on what is relevant versus what isn’t.
• Impact: Often when you are proposing a research project, you would be asked about its intended impact- on the society, academia and industry. To some extent, the impact is governed by the approach meaning that the impact of your peers could be different from that you can make if your approach is different. A thorough literature survey can help you establish the nature of impact of your proposed contributions.

So, as you can see from the relative extensive list of benefits of conducting a thorough literature review in scientific research, literature review is indeed a very important step. So, let us look into when and how to conduct the literature review.

The importance of literature review is often the highest during the early days of planning a research project. With time however, further passes of literature review are done just as a sanity check to re-evaluate any recent advances. The depth and level of detail might vary depending on whether you are doing this appraisal for a conference manuscript or for a PhD thesis, but overall the process would be quite similar.

Writing a literature review comprises of a range of soft skills like gathering, prioritizing, reading, evaluating, note taking and summarizing the peer-reviewed articles. As you might imagine, with time, this can easily get out of hand if you do not have an agile system in place. While there are many ways of doing this, but I have prepared a FREE to use Notion template to help you plan and manage your literature review database . Feel free to replicate the template and adapt it to your needs.

You could also do the literature review the old school way wherein you scribble notes onto printed documents but sifting through them will get cumbersome. So, I would recommend opting for one of the easy to use digital tools especially as this allows you to maintain, search and sort the database as needed.

If you are conducting the literature review for the very first time, you might be feeling overwhelmed with how to go about it so here is a step-by-step guide for you:

• Step-1 (Keyword): Make a list of a broad keyword that is highly relevant to your area of research. Then make a few different variations of this keyword to make a bag of keywords.

At this stage, you would also start discovering various research databases where such peer-reviewed articles are typically indexed. Perhaps you can try to search with those directly as time progresses as search engines would also pick up other publications like books, media articles and so on which are not directly relevant for literature review. 

• the authors,
• their affiliations,
• publication venue,
• publication date,
• strengths and weaknesses-  Remember not to plagiarize. Instead, write this bit in your own words to avoid plagiarism from propagating onwards to your manuscripts and thesis.  
• Step-4 (Clustering): Once you have an extensive database, you should try and see if you can form data clusters. While every paper might appear to be a standalone contribution, this is hardly the case. There will be research overlaps and gaps which is what you are trying to discover by clustering. Also, the size and density of the clusters will help you evaluate the level of competition within the cluster and will help you position your own research contributions.  

Once your group is in place, conduct a free-flow discussion, scribble notes on a white board, or make a presentation, but the key idea here is to discuss what you learnt and concluded and debate it with others to ensure you haven’t misinterpreted or missed anything. Reader’s bias is very real in conducting solo literature review so such an exercise can help fix such biases. 

One caveat though, often the early stage researchers think of the literature review as a one time exercise. As it turns out, literature review database as actually time sensitive- meaning the importance of a literature review database diminishes without outdated content. So, with the passage of time, you would want to filter out the “old” citations and look for their recent extensions or swap them out with other relevant works. This will help ensure that the literature review is kept up-to-date so that you are basing your claims on recent data.

The frequency at which you would need to update this literature review database depends on the rate of progress of your niche. Ideally, your literature review database is considered relevant if you have the past 5-7 years of articles in your collection, though these numbers are arbitrary.

Literature review or literature survey is often the precursor to planning a research project and proposing to invest significant efforts in it. The main idea behind this appraisal is to clearly understand who the closest competitors are, what is the current state-of-the-art in the field and what are the limitations that you plan to address as a part of your research proposal . The more thorough you are with your literature review, the more confident you can be with your proposal to pursue a certain research topic while providing evidence.

Another key thing to keep in mind when it comes to literature review is that, the literature review database you prepare needs to be constantly updated with time as an outdated database would mean somebody else might have already beaten you to the punch and you are trying to reinvent the wheel thereby wasting efforts. The frequency of update of this database needs to be aligned with the rate of advancement in your particular field.

A literature review is not only a summary of key sources, but  has an organizational pattern which combines both summary and synthesis, often within specific conceptual categories . A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem. The analytical features of a literature review might:

• Give a new interpretation of old material or combine new with old interpretations,
• Trace the intellectual progression of the field, including major debates,
• Depending on the situation, evaluate the sources and advise the reader on the most pertinent or relevant research, or
• Usually in the conclusion of a literature review, identify where gaps exist in how a problem has been researched to date.

The purpose of a literature review is to:

• Place each work in the context of its contribution to understanding the research problem being studied.
• Describe the relationship of each work to the others under consideration.
• Identify new ways to interpret prior research.
• Reveal any gaps that exist in the literature.
• Resolve conflicts amongst seemingly contradictory previous studies.
• Identify areas of prior scholarship to prevent duplication of effort.
• Point the way in fulfilling a need for additional research.
• Locate your own research within the context of existing literature [very important].
