The patients were divided into groups of less than 50%, 50–85%, and 85% success rate depending on the rate of successful ballooning procedures per target site. ** p < 0.01 vs. baseline. *** p < 0.001 vs. baseline. ^† p < 0.05 compared with the below 50% group at each time point. ^†† p < 0.01 compared with the below 50% group at each time point. ^††† p < 0.001 compared with the below 50% group at each time point. The data are presented as estimated mean ± 95% confidence interval.
