  1. Median and first, as well as third quartile limits (median [q1; q3]) are shown for non-normally distributed, continuous variables. For normally distributed, continuous variables, data are given in mean ± standard deviation (mean ± SD). For categorical parameters, total numbers (percentage) are shown. Significant p-values are depicted in bold.
