Evidence
synthesis
Comprehensive Meta-analysis software is used to compare the efficacy and
safety of and control. The Odds ratio (OR) with 95% confidence interval
(CI) was used for dichotomous variables. We conducted a pairwise
meta-analysis for our analysis and reported summary effect estimates
along with 95% confidence intervals (CIs) for each direct comparison.
We included studies that provided data for at least two comparisons. The
heterogeneity is defined as I2>50% and P <0.1.
The random and fixed effect models were used for high and low
heterogeneity studies, respectively.
