Statistical analysis
We examined the heterogeneity assumption using Cochran’s Q test and quantified it using Higgins I2 statistic, withI2 > 50% considered statistically heterogeneous. We used bivariate mixed-effects regression model to calculate pooled sensitivity and 95% confidence intervals (CI). We performed meta-regression and subgroup analysis to investigate the potential impact of variates on sensitivity and the source of heterogeneity. Results were displayed graphically on forest plots. We conducted sensitivity analysis to evaluate the robustness of the results by removing studies with high weight or debatable methodology, modifying stratified criteria, or altering statistical model. We did all statistical analyses with STATA (version 15.0; Stata Corporation, College Station, TX, USA)
