Differences between groups were tested with the Mann-Whitney U-test for continuous variables, and with the Chi-squared test or Fisher’s exact test for categorical variables.

Data are presented as median with P₂₅-P₇₅ given between brackets.

Data are presented as number with percentages.

Data on the duration of the physical therapy were only collected in the 96 patients that participated in the gait analysis study
