At the last follow-up of @ months , the success rate in the R&R ( @ % ) group was significantly higher than those in the UMR ( @ % ) and BMR ( @ % ) groups ( p = @ and @ ) ; the mean exodeviations at distance and near in the R&R group were significantly different from those in the UMR and BMR groups ( p = @ and @ ) ; there were no significant differences in the mean near-distance differences between the R&R group and the other two groups ( p > @ ) .
