n = number of observations; Md = median; IQR = interquartile range; SD = standard deviation; difference across gender: *** p < 0.001, ** p < 0.01, * p < 0.05. We used univariate Student’s t-tests for continuous variables and Chi-square-tests for categorical variables to assess univariate group differences.
