Continuous variables are described by mean values with standard deviation in brackets (SD) or median values with 1st and 3rd Quantil in brackets (Q1 / Q3) if they are skew. Discrete variables are described through relative and absolute frequencies. Baseline data were compared by Chi-square test for dichotomous variables, t-tests for normally distributed continuous variables, and Wilcox rank sum test for more skewed continuous data
Note: In the comparison of participants who are depressed with those not depressed, all variables differed significantly
