Conclusion
In Brief
The main aim of any research is making relevant  
contribution to the field of research in a field and to be 
 able to add relevant content to the ‘conversation’.
To achieve this, one must begin by understanding the
context of the ‘conversation’.
And this important task is done by a properly conducted 
 and documented review of literature.
Need for  
Biomedical research is increasing exponentially in the last few 
Literature in  decades necessitating the need for dedicated medical writing
 Research  s ervices with domain-related expertise.
Article and  
Biomedical literature review is the first step towards any research.
Dissertation
L iterature review explores previous research conducted in the field 
 of interest, the limitations and conflict areas identified and the 
need  for further research.
It also helps one in understanding and formulating one’s area of  
research in a better manner and justifies the methodology used.
Contd..
L iterature review helps connect the statistical findings of the research 
with  prior research statistics.
Review helps in preventing duplication of research and avoiding redundant 
 fields and is needed for good quality research paper.
Dissertation is an important requirement for completion of academics and 
 literature review is an important part of this academic requirement.
Use of  
Literatur I ntroduction to a primary research topic – This sets the  context for the research article or dissertation by 
e  Review analysing  previously published literature.
S ystematic review –It is related to meta-analysis 
and provide a  quantitative or less often qualitative statistic 
summarizing  several papers.
S econdary data analysis projects- It is a research 
project  on its own and begins with a clear r esearch 
question.
Sources 
of  Data
Data has been sourced from libraries as well as
digital sources.
This is a cumbersome activity which continues  
throughout all the stages of the study and hence, it 
 should be started early in the phase of research.
Citation Picking up articles for review is another art and one should 
s  have clear inclusion and exclusion criteria to perform a  
relevant review.
Adequate number of citations is often defined by the
journal and that needs to be followed.
Citations should include those studies that are
inconclusive or require further research.
Critical appraisal of the studies cited with an analytical 
 review of the same is desirable.
Organisin There are several ways to organize biomedical  l
g  Data iterature  r eview and are used by PhD students for their 
biomedical  dissertations.
Scientific manuscript writing services commonly use
chronological sequence for listing out literature for review.
Another method often used in s cientific article writing is a
well-argued format grouping.
A reverse-triangle approach is where we start discussing  
based on the broader concepts and then gradually narrow in 
 onto the topic of interest.
Contd..
A similar approach involves starting with the known facts supported by  
literature and then moving to the grey zones and the less known to the 
 unknown debated areas.
Depending on the requirement of the topic of literature research, what is the  
outcome needed out of the literature search in context of the objective of the 
 current study.
Future 
 
L iterature review guidelines need to be defined in 
Scope more  precise terms.
s
There are many shortcomings in the review of 
literature
in the absence of uniformity of performing this task.
Bias is to be reduced by clear definition of the
methodology that is the need of the hour.
Conclusion
With increase in the number of publications, it becomes  
important to set the factual context of the current research 
 study that one wishes to get published.
This is relevant to participate in the ongoing ‘dialogue’ on the 
 subject and contribute positively to that area of research.
A thorough and relevant review of literature is paramount 
 for this.
