INTRODUCTION   
Rationale 6 Describe the rationale for the review in the context of what is already known 3–4 24–55
Objectives 7 Provide an explicit statement of the question(s) the review will address with reference to participants, interventions, comparators, and outcomes (PICO) 4 56–63
METHODS   
Eligibility criteria 8 Specify the study characteristics (such as PICO, study design, setting, time frame) and report characteristics (such as years considered, language, publication status) to be used as criteria for eligibility for the review 4 56–58
4–5 69–91
Information sources 9 Describe all intended information sources (such as electronic databases, contact with study authors, trial registers or other grey literature sources) with planned dates of coverage 6 92–114
Search strategy 10 Present draft of search strategy to be used for at least one electronic database, including planned limits, such that it could be repeated Table 2 Table 2
Study records:     
 Data management 11a Describe the mechanism(s) that will be used to manage records and data throughout the review 7 116–117
 Selection process 11b State the process that will be used for selecting studies (such as two independent reviewers) through each phase of the review (that is, screening, eligibility and inclusion in meta-analysis) 7 119–126

Risk of bias in individual studies 14 Describe anticipated methods for assessing risk of bias of individual studies, including whether this will be done at the outcome or study level, or both; state how this information will be used in data synthesis 8–9 153–169
Data synthesis 15a Describe criteria under which study data will be quantitatively synthesised 9 171–188
15b If data are appropriate for quantitative synthesis, describe planned summary measures, methods of handling data and methods of combining data from studies, including any planned exploration of consistency (such as I2, Kendall’s τ) 9 171–188
15c Describe any proposed additional analyses (such as sensitivity or subgroup analyses, meta-regression) N/A N/A
15d If quantitative synthesis is not appropriate, describe the type of summary planned 10 184–188
Meta-bias(es) 16 Specify any planned assessment of meta-bias(es) (such as publication bias across studies, selective reporting within studies) NA NA
