  • Registration: If registered, provide the registration number and registry name.

Introduction

• 3. Rationale: Describe the rationale for the review in the context of what is already known.
• 4. Objectives: Provide an explicit statement of the question(s) the review will address with reference to participants, interventions, comparators, and outcomes (PICO).

Methods

• 5. Eligibility criteria: Specify the study characteristics (e.g., PICO, study design, setting, time frame) and report characteristics (e.g., years considered, language, publication status) to be used as criteria for eligibility for the review.
• 6. Information sources: Describe all intended information sources (e.g., electronic databases, contact with study authors, trial registers, or other grey literature sources) with planned dates of coverage.
• 7. Search strategy: Present a draft of the search strategy to be used for at least one electronic database, including planned limits, such that it could be repeated.
• 8. Study records: data management: Describe the mechanism(s) that will be used to manage records and data throughout the review.
• 9. Study records: selection process: State the process that will be used for selecting studies (e.g., two independent reviewers) for inclusion in the review.
• 10. Study records: data collection process: Describe the process of data extraction, including how it will be done and who will do it.
• 11a. Data items: List and define all variables for which data will be sought, including PICO and other relevant data for the review.

• 12. Risk of bias in individual studies: Describe the planned method for assessing risk of bias in individual studies, including how it will be used in data synthesis.
• 13. Data synthesis: Describe the planned methods of data synthesis, including a description of the summary measures and any planned investigation of heterogeneity.
• 14. Meta-bias(es): Describe any planned assessment of meta-bias(es) (e.g., publication bias, selective reporting within studies).
• 15. Confidence in cumulative evidence: Describe how the strength of the body of evidence will be assessed.

Other
