The QUORUM statement on how to report a systematic review

Heading/subheading	Descriptor
Title	Can clearly determine that report is a systematic review.
Abstract	Uses a structured format.
Objectives	Describes clinical question explicitly.
Data sources	Lists the databases used and other sources of data.
Review methods	Describes the process of how data was selection, quality assessment, data extraction, and any meta-analysis performed.
Results	Describes included and excluded studies and the results of any meta-analysis.
Conclusion	Describes the main results.
Introduction	Discusses the clinical problem, why the intervention may work, and the reasons for performing the review.
Methods
Searching	Describes the data sources (eg, databases, handsearching, registers, researchers) and any search exclusions (date, language).
Selection	Inclusion and exclusion criteria outlined.
Validity assessment	Describes how any quality assessment was performed.
Data abstraction	Discusses how data was extracted from studies.
Quantitative data synthesis	Information on how data was combined (meta-analysis), including statistical methods used, measures of effect, and any sensitivity and subgroup analysis performed. Also explains which tests were performed, looking for heterogeneity and publication bias.
Results
Trial flow	Provides a figure showing the number of studies screened, included, and excluded at each step.
Study characteristics	Each trial is described briefly, including participant demographics, number of participants, intervention, and follow-up.
Quantitative data synthesis	Presents simple summary results for individual studies and any meta-analysis performed.
Discussion	Discusses the answer to the original question in the light of the best available evidence and any possible biases. Also suggests future research.
