Systematic literature review methods

Before starting a systematic review, you should search these databases for any registered reviews on the topic of your choice. A systematic review of reviews can provide reassurances that the conclusions of individual reviews are consistent, or not.

The process of identifying and appraising all published reviews allows researchers to describe the quality of this evidence base, summarise and compare the review's conclusions and discuss the strength of these ological challenges and possible solutions are described within the context of (i) sources, (ii) study selection, (iii) quality assessment (i. The review systematically searches, identifies, selects, appraises, and synthesizes research evidence relevant to the question using methodology that is explicit, reproducible, and leads to minimum bias.

Systematic reviews (or overviews) of reviews are a logical and appropriate next step, allowing the findings of separate reviews to be compared and contrasted, providing clinical decision makers with the evidence they methods used to identify and appraise published and unpublished reviews systematically, drawing on our experiences and good practice in the conduct and reporting of systematic reviews are described. This can help the reviewers to delineate clearly if they wish, for example, to compare and summarise systematic reviews that address the same treatment comparison or a particular intervention for a population or condition, or a range of interventions for people with a specific condition.

For example, in our review of reviews on fetal fibronectin and transvaginal cervical ultrasound for predicting preterm birth, [8] we included reviews that had incorporated studies among women who were both symptomatic and asymptomatic for preterm birth.

It is important to be specific in reporting the primary outcome of interest for the review, and this can reduce workload by limiting data extraction to only those results relevant to the topic of interest from reviews that report on several outcome measures. In such instances, this limitation should be acknowledged when reporting the review and it might be worthwhile reporting the difference between searches with and without language restrictions in order to estimate the amount of literature that might have been search terms used for the literature search should be clearly described, with information on their relevance to the research question.

Peer review ds of studies of maternity care interventions have been published, too many for most people involved in providing maternity care to identify and consider when making decisions. Comparability of included reviews: are the reviews comparable in terms of eligibility criteria, study characteristics and primary outcome of interest?

Jadad et al (1997) provide guidance on how to address discordant results from individual reviews [31] and conducting systematic reviews of reviews will help to address this issue further. This will ensure that you are not duplicating is the best approach to conducting a systematic review?

Reporting items for systematic reviews and meta-analyses (prisma) statement, "an evidence-based minimum set of items for reporting in systematic reviews and meta-analyses".

Furthermore, researchers might find that identifying and highlighting a recent high quality systematic review will prove of most benefit to decision makers using their review or reviews. Likewise, although the search for a review of individual studies might need to cover many decades [19], limiting the search to period from the early 1990 s onwards is likely to identify all but the very small minority of systematic reviews conducted before then [20, 21].

Grey literature includes unpublished studies, reports, dissertations, conference papers and abstracts, governmental research, and ongoing clinical trials. Reviews often, but not always, use statistical techniques (meta-analysis) to combine results of eligible studies, or at least use scoring of the levels of evidence depending on the methodology used.

This may prove relevant in learning of published systematic reviews that are not indexed in the bibliographic databases searched, and of ongoing systematic reviews near completion. Applying language restrictions is not recommended; but, unavoidable constraints such as a lack of access to translation services or funds to pay for these may make it necessary to restrict the systematic review or reviews to english language publications.
