Statistical analysis
PEW
Statistical analysis was performed using SPSS software (version 26.0). Continuous variables were presented as mean ± standard deviation (SD). Categorical variables were presented as numbers and proportions. Comparison of baseline patients’ characteristics between groups was assessed using the Chi-square test or independent sample t-tests, as appropriate. Comparisons of patient characteristics at the start and end of the study within each group, as well as at the end of the study between groups, were assessed using mixed-design repeated measures ANOVA with Bonferroni post-hoc correction for pairwise comparisons. Differences in French PEW scores at the start and end of the study within each group were evaluated using the Wilcoxon signed-rank test, and between the two groups at month 3 using the Mann-Whitney U test.
