  1. Data are presented as frequency (percentage) for categorical variables and mean ± standard deviation (SD) for continuous variables if normally distributed and medians (interquartile range, IQR) if not. P values were derived from Pearson’s chi-square test and Student’s t-test for parametric comparisons and the Mann-Whitney U test for nonparametric comparisons. Q1: 25th percentile. Q3: 75th percentile
