REGRESSION
The Kolmogorov–Smirnov test was used for normality checking. Due to the non-normal distribution of the data, continuous variables are presented with the minimum, maximum, and median (interquartile range, IQR), and categorical variables are presented with frequencies (percentages). Groups were compared using the non-parametric Mann–Whitney U test, linear regression analysis, and Wilcoxon Signed Ranks test.
