(Search strategy)
Seven databases and research registries will be searched by a searcher. FFC database will be searched and omitted related studies will be added to the review. The studies found by other methods will be added.
(Selection and data collection)
It will be conducted based on eligibility criteria independently by two reviewers. Disagreements will be resolved by discussion between the reviewers.
(Risk of bias)
It will be assessed independently by two reviewers using modified check list (13 items) of Cochrane Handbook for interventional trials. Disagreements will be resolved by discussion between the reviewers. The agreement rate and the kappa coefficient will be calculated. Studies with a high risk of bias will not be adopted.
(Indirectness)
It will be evaluated independently by two reviewers.
(Data synthesis)
A meta-analysis will be performed using RevMan Web. Studies with missing 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. Sensitivity analysis and sub-group analysis will be performed excluding studies with extremely large sample sizes and only in RCTs.
(Imprecision)
It will be assessed based on the total number of participants.
(Inconsistency)
It will be evaluated by the I square value and statistical test in a meta-analysis.
(Publication bias)
It will be assessed from Funnel plot in a meta-analysis.
