2.4. Statistical Analyses

Statistical analyses were performed using IBM-SPSS Statistics (version 25, 2017, IBM Corporation, Armonk, NY, USA). Parametric data are expressed as means ± standard deviation (SD) or 95% confidence interval. Baseline differences in the mean walking speed of T1–T2 (T1–T2 mean walking speed) by sex, disease, and mRS scores were examined using the t-test and one-factor analysis of variance (ANOVA). To compare and analyze the effects of the time period, sex, and the T1–T2 mean walking speed (Fast group (≥1.0 m/s) and Slow group (<1.0 m/s)), ANOVA with the mixed-effects model for repeated measures (MMRM) was performed, with the Bonferroni test as the post hoc test. In all cases, p values less than 0.05 were considered significant.
