  1. M median, Q1 25th percentile, Q3 75th percentile
  2. *The difference was obtained by subtracting the first follow-up score from the last follow-up score
  3. **Since the data are not parametrically distributed, z: Wilcoxon analysis was used
  4. ***Since the data are not parametrically distributed, z: Mann-Whitney U test was used
