Is there uncertainty and debate? Is there demonstrable variation in practice? Is there a need to inform the design and conduct of a definitive, large trial? Are the findings novel? Has the question been adequately addressed by a previous systematic review and how recently?

Define the research question clearly and completely Check that the research question is unresolved Include an experienced meta-analyst, content expert ideally, a triallistand statistician Write a detailed study protocol outlining end points, inclusion criteria, and a search strategy, and publish it in advance on a publically available website e.

PROSPERO 6 Be circumspect when interpreting the results; acknowledge the sources of bias; and consider heterogeneity, generalizability, and contemporary clinical relevance Report the study in such a way as to allow reproducibility of the results PRISMA 5 or future updating of the systematic review What is the contemporary relevance of the study question?

PROSPERO 6 Be circumspect when interpreting the results; acknowledge the sources of bias; and consider heterogeneity, generalizability, and contemporary clinical relevance Report the study in such a way as to allow reproducibility of the results PRISMA 5 or future updating of the systematic review View Large Like any other paper, the SR has an introduction, a methods section, a results section, and a discussion.

What makes the SR different is that the study data are derived from the reports of completed and usually published studies, and it does this in a very systematic way.

Before even starting the process of performing an SR, the authors should clarify their clinical question using the PICO participants, intervention, comparison, and outcomes approach.

Recently, however many other types of SRs are being done that may not necessarily fit this formula. Examples include diagnostic reviews, prognostic reviews, and qualitative reviews. The methodology for these reviews is still under development and will not be considered further in this editorial.

The clinical question should be described in detail at the protocol stage. The participants are the group of patients to be included.

It is important to consider the characteristics of these thoroughly in order to include the group of patients relevant to the question in focus. The intervention must likewise be well described, whereas the control can be placebo, no treatment, or standard care.

Of course, two different treatments can also be compared. There needs to be a nominated primary end point in any trial, including SRs.

The PICO is useful when designing the search strategy for the review. Subgroups and covariates should be carefully considered and prespecified in order to avoid data dredging. As the main interest is usually the reported effect size, it is worthwhile for meta-analyses to consider inclusion of abstracts from major conferences in recent years.

The search strategy is part of the review methodology, although for some journals it can be described as supplementary material on the journal website. The search methods need to be written in such a way that the search can be repeated by the reader, and by the authors, in case of updating the review.

The review process will start by retrieving and selecting relevant papers for inclusion as described in the protocol. Every paper must be evaluated to determine whether it meets the inclusion criteria.

It is recommended to make a table of all included papers, and that the search and screening be done independently by at least two investigators.

Double-data extraction by two independently working researchers is recommended to prevent errors. It is useful to provide a flow diagram describing the selection of papers for the review.

The SR protocol should be published before starting the review process. For Cochrane reviews, publication of the protocol has been standard procedure since the foundation of the Cochrane Collaboration in After selection, the papers must be screened for bias.

Meta-analysis should be performed only when appropriate. There are two major factors that need to be evaluated before a decision about meta-analysis is made; one is heterogeneity between studies and the other is the existence of reporting bias.

Heterogeneity arises when the difference between trials is too big. The differences can be in the populations or in the interventions. The amount of heterogeneity can be quantified using the I2 statistic.

It arises when the result of a trial has an impact on the publications process. It is well known that a trial with a positive, significant result is more likely to be published faster time lag biasin a journal with a higher impact factor publication biasin English language bias than its non-significant counterpart, even if both trials are performed according to the highest standards of methodology.Here is the first book every prospective doctoral candidate should read.
