  1. Data are presented as mean ± standard deviation where applicable. Values inside brackets are presented as median (interquartile range, 25th–75th percentile).
  2. TW tendon width.
  3. *Statistically significant (P < 0.05).
  4. aChi-square test; for the others, the Mann–Whitney U test was used.
