P style="text-align: justify;">references: the references section of a systematic review article usually contains an extensive number of references.

However, in a systematic review of reviews, it may be possible to limit the searches to databases specific to systematic reviews such as the cochrane database of systematic reviews and the database of abstracts of reviews of effects. Researchers have recognised this problem and many have accepted the challenge of preparing systematic reviews of individual studies in order to appraise, summarise and bring together existing studies in a single place.

A systematic review of reviews can provide reassurances that the conclusions of individual reviews are consistent, or not. 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.

During the planning phase, before commencing the systematic review of reviews, a review team should be established. Although the researchers will usually have to do this via an assessment of the quality of report, with the hope that initiatives such as prisma (formerly, quorom) which assist by facilitating adequate standards of reporting [26].

They proposed several solutions, including limiting studies in meta-analyses and reviews to registered clinical trials, requiring that original data be made available for statistical checking, paying greater attention to sample size estimates, and eliminating dependence on only published of these difficulties were noted early on as described by altman: "much poor research arises because researchers feel compelled for career reasons to carry out research that they are ill equipped to perform, and nobody stops them. For example, in our review on interventions for preventing preterm birth [6], we restricted the inclusion criteria to reviews of randomized controlled trials.

For example, some systematic reviews on antibiotic therapy for the prevention of preterm birth [29, 30] report a variety of outcome measures other than preterm birth (e. Reviews address the probable course or future outcome(s) of people with a health ews of systematic reviews (oors) are a new type of study in order to compile multiple evidence from systematic reviews into a single document that is accessible and useful to serve as a friendly front end for the cochrane collaboration with regard to healthcare cochrane collaboration provides a handbook for systematic reviewers of interventions which "provides guidance to authors for the preparation of cochrane intervention reviews.

In recent years however, decision makers who were once overwhelmed by the number of individual studies have become faced by a plethora of reviews [4, 5]. In developing the search strategy for a systematic review of reviews, researchers might wish to consider the press initiative, developed as a means for peer reviewing literature searches [24] to check that the various elements of the electronic search strategy have been considered.

38] subsequently, a number of donors – most notably the uk department for international development (dfid) and ausaid – are focusing more attention and resources on testing the appropriateness of systematic reviews in assessing the impacts of development and humanitarian interventions.
