Search strategy: Six databases will be used for the search in this study. We will search from the beginning of each database to the search date.
Selection and data collection process: Screening and data extraction based on eligibility criteria will be conducted. Disagreements and uncertainties will be resolved by discussion between the reviewers.
Risk of bias assessment and indirectness evaluation: A full quality appraisal of these papers will be made using modified check list of Cochrane Handbook for interventional trials. Disagreements and uncertainties will be resolved by discussion between the reviewers. Studies evaluated as having a high risk of bias will not be adopted.
Data synthesis: A meta-analysis will be performed using RevMan after the reviewers confirm the absence of heterogeneity. Studies with missing or uncertain data will be excluded if no data is available by contacting the author. If not suitable for integration, a qualitative assessment will be carried out. Estimated heterogeneity and publication bias will be assessed from I square value in Forest plot and Funnel plot, respectively.
Imprecision assessment: Imprecision will be assessed based on the total number of participants in all included studies.
Inconsistency evaluation: Inconsistency will be evaluated by the I square value and statistical test for heterogeneity in a meta-analysis. If a meta-analysis cannot be performed, it will be assessed from the percentage of studies that have had a significant effect.
Publication bias: It will be assessed from Funnel plot in a meta-analysis. If a meta-analysis cannot be performed, it will be assessed from the reporting status of studies registered in research registries.
Sensitivity analyses and sub-group analyses: These analyses will be conducted according to the following items: the analysis excluding studies with extremely large sample sizes, the analysis limited to RCTs, and the analysis divided by measurement sites.
