CI: Confidence interval; RR: Risk ratio; a: Meta-analysis included only one pulp condition; b: Meta-analysis included studies that performed only one visit; c: Total number of events is less than 300; d: Upper or lower confidence limit crosses the effect size is greater than 25% of estimated effect in either direction
