- aComplications evolving to spontaneous remission or not requiring intervention or not persisting chronically
- bComplications requiring intervention or persisting chronically
- cComplications from the start of the procedure up to 7 days
- dComplications beyond 7 days of the procedure
- A full description of minor and major complications is described in Additional file 2
- Abbreviations: OR Odds Ratio, CI Confidence Interval
- The reported p-value 1 was based on the comparisons of outcomes between two groups using Chi-squares where the number of events and total sample size were obtained by pooling all the studies
- The reported p-value 2 was based on the weighted logistic regression, where the weight was defined based on the sample size of each study
