Outline

In-Brief

Systematic literature (Qualitative, non-meta-analysis) review writing is a protocol-driven process that demands researchers to extract, analyse and present an exhaustive summary of the latest yet apt literature for their specific studies in the prescribed format along with bias/evidence quality figures. It primarily focuses on clear, structured questions that need to be answered using an in-depth search strategy. Systematic review authors should decide ahead of time what information will be needed for their precise review and build up a technique for acquiring them. Although there are several software’s (e.g., Covidence, Colandr, Rayyan, CREBP, EPPI-Reviewer 4, Distiller, JBI SUMARI tool, Systematic Review Data Repository (SRDR), Systematic Review Toolbox available for collecting data, its researchers’ knowledge and skills play a major role in the extraction.

What Should Extracted Data Should Help us to Drive

The data extracted should sufficiently depict theincludedinvestigations,supportthe

development of tables and figures, encourage the risk of bias assessment, and empower syntheses and meta-analyses.

Review authors ought to acquaint themselves with detailing rules for systematic review and the PRISMA statement; to guarantee that significant components and areas are incorporated.

Items to be considered for Data Extraction and Writing a Systematic Review

1. Eligibility and Documenting decisions:

Confirm qualification of the examination for the review including reference (first author/year/journal citation)

Visually scanning references lists from relevant studies

Contd...

Data extractor name, data extraction date, identification features of a report from which we are going to extract the data is also part of the extraction process.

Country Location

Race / Religion if its important

Handsearching key journals from identified studies

Contacting study authors, experts, manufacturers, and other organizations Citation searching

Reasons for exclusion of the study.

2. Study Location and Demographic Details:

Gender Age

Medical Condition (DM or HTN)

Contd...

Contd...

Study plan:

Parallel, factorial, hybrid, bunch parts of the plan for randomized preliminaries, and additionally study configuration highlights for non-randomized examinations.

Single or multicenter study; if multicenter, a number of enlisting focuses.

Recruitmentandtestingmethodsutilized(countingatthedegreeofindividual members and bunches/destinations if significant).

Enrolment start and end dates; length of member follow-up.

Contd...

3. Study Techniques:

Details of irregular arrangement age, distribution grouping covering, and veiling for randomized preliminaries, and strategies used to forestall and control for perplexing, choice predispositions, and data inclinations for non-randomized investigations.

Methods used to forestall and address missing information.

4. Statistical Analysis:

Analysis unit (for example, singular member, Centre, town, body part)

Statistical techniques utilized whenever registered impact gauges are separated from reports, incorporating any covariates remembered for the measurable model.

Contd...

Likelihood of revealing and other biases.

Funding sources or other material help for the study.

Authors' monetary relationship and other possible irreconcilable circumstances.

5. Participants

Setting

Region(s) and country/nations from which study members were enlisted Study qualification measures, including symptomatic rules

Contd...

Qualities of members toward the start (or gauge) of the investigation (for example, age, sex, comorbidity, financial status).

6. Intervention

Components,coursesofconveyance,portions,timing,recurrence,intercession conventions, length of mediation

Factorspertinenttoexecution(forexample,staffcapabilities,hardware prerequisites)

Contd...

The integrity of intercessions (for example, how much indicated methodology or segments of the mediation were executed as arranged)

Description of co-intercessions

Definitionof'control'gatherings(forexample,nointercession,faketreatment, negligibly dynamic comparator, or segments of regular consideration)

Components, portion, timing, recurrence

intercessionstatuswas

Contd...

For each pre-indicated result area (for example, uneasiness) in the systematic review:

Whether there is proof that the resulting space was evaluated (particularly significant if the result was surveyed yet the outcomes not introduced.

Measurement apparatus or instrument (counting meaning of clinical results or endpoints); for a scale, name of the scale (for example, the Hamilton Anxiety Rating Scale), upper and lower cutoff points, and whether a high or low score is good, meanings of any limits if fitting.

Contd...

7. Outcomes

Specific metric (for example, post-intercession anxiety, or change in uneasiness from pattern to a post-meditation time point, or post-meditation presence of nervousness (yes/no))

Method of total (for example, the mean and standard deviation of tension scores in each gathering or extent of individuals with nervousness)

Timing of result estimations (for example, appraisals at the end of the eight-week intercession period, occasions happening during the eight-week mediation period)

Adverse results need exceptional consideration relying upon whether they are gathered methodically or non-deliberately (for example, by deliberate report).

Contd...

For each group, and for every result at each time point: number of members arbitrarily relegated and remembered for the study; and number of members who pulled out, were lost to follow-up or were rejected (with purposes behind each)

Summary information for each group (for example, 2×2 table for dichotomous information; means and standard deviations for consistent information)

Between-bunch appraises that evaluate the impact of the intercession on the result, and their accuracy (for example, hazard proportion, chances proportion, and mean contrast)

Contd...

8. Results

If subgroup investigation is arranged, similar data should be extricated for every member subgroup.

9. Miscellaneous

Key conclusion of the author.

Reference to other pertinent investigations Correspondence required

Miscellaneous remarks from the author of the study or by the review authors.

Further remarks by the study authors, for instance, any clarifications they accommodate startling discoveries, might be noted.

Contd...

References to different studies that are referred to in the investigation report might be helpful, in spite of the fact that review authors ought to know about the chance of reference inclination.

Documentation of any correspondence with the examination creators is significant for review straightforwardness.

Conclusion

Preferably, data just should be extricated once and ought to be put away in a safe and stable area for future updates of the survey, whether or not the first review authors or an alternate gathering of authors update the Systematic review.

Review authors have the chance to work with trial lists, diary editors, funders, controllers, and different partners to make study information (for example, CSRs, IPD, and some other type of study information) freely accessible, expanding the straightforwardness study.
