How to write a systematic review of literature in the scientific research paper: Pubrica.com

The systematic review shall be carried out to synthesize the evidence of multiple academic studies in order to answer a specific research issue in a way that is reproducible and straightforward, thus attempting to include all the published evidence on the subject accompanied by an evaluation of the quality of the evidence.

The systematic review remains one of the best forms of evidence and eliminates the prejudice found in other approaches Systematic reviews have become the dominant approach in the areas of public policy of health and health sciences. Previously, Some have suggested that systemic analysis should be subject to a systematic review, but the little direction is available. The segment offered a description of the various steps involved in carrying out a systematic review. Such knowledge should provide sufficient guidance to those who are performing a systematic literature review (Davis, 2019 ).

Key characteristics of the systematic review:

1. Identification of a research question
2. Inclusion & exclusion criteria
3. Rigorous & systematic search of the literature
4. Critical appraisal of included studies

Different types of systematic review:

The systematic review mainly classified into three types, including

1. Meta-analysis
2. Quantitative analysis
3. Qualitative analysis.

Steps to be followed before drafting a systematic review:

1. Identification of a research question:

It is important to identify the study concern before conducting a systematic review of the literature. For eg, why is this survey essential? What kind of problem should be answered? A number of frameworks/tools are available to support this method, such as SPIDER, PICOS/PICO, SPICE and PEO criteria. Such kinds of structures help to break down the question into the related sub-components and link them to definitions, to draw up a formalized search criteria. This move is important for the discovery of literature related to the topic (Jahan et al., 2016 ).

2. Inclusion and exclusion criteria:

It is important to determine the eligibility criteria before starting the systematic review, including methods, study design, set criteria for the topic and the methodological quality of studies.

3. Guidelines for systematic review:

Researchers widely follow the PRISMA guidelines in Systematic review writing. The PRISMA recommendations instruct scholars on how to conduct a systematic review, which involves a flow diagram and a 27-item checklist. The protocol of the instructions for PRISMA.

4. Screening of the articles

5. Data analysis

The systematic review should be in the following structure:

1. Abstract
2. Introduction
3. Methods
4. Results
5. Discussion
6. Conclusion

Key points:

1. A systematic review of the literature tends to be one of the most trusted sources of high-quality information for clinical decisions.
2. Knowing the elements of the review will help practitioners assess their output more effectively.
3. Many formal structures help organize and monitor evaluations, for which reproducibility is recommended.
