For primary objective
Findings of the review will be presented via “the characteristics of included studies” and “summary of findings” table (as shown in Table 0 to 40%: might not be important30 to 60%: may represent moderate heterogeneity50 to 90%: may represent substantial heterogeneity75 to 100%: considerable heterogeneityRandom effects model with and inverse-variance approach, i.e., DerSimonian and Laird method will be used for meta-analysis [A narrative synthesis will be performed in case of high heterogeneity and when meta-analysis is not possible, i.e., due to the presence of “clinical,” “methodological,” and “statistical.” In the narrative synthesis, the outcome and findings will be reported narratively, and tables/figures will be used for explanation.If it is possible, sub-group analyses will be performed based on geographical location, age, gender, type of physical activity, etc. If sufficient data is available, we will perform sensitivity analysis for assessing the robustness of the results.
