Note: SD=standard deviation; IQR=interquartile range

P-values are based on non-parametric exact Wilcoxon rank-sum tests for continuous variables and Fisher’s exact tests for categorical variables

Effect sizes are based on η² (eta-squared) for continuous variables (small: 0.01, medium: 0.06, large: >0.14) and Cramer’s V for categorical variables (small: 0.10-0.29, medium: 0.30-0.50, large: >0.50).
