Note: Median values are presented with interquartile range (Q 1 –Q 3 ) and mean values with standard deviation (SD). p -Values were calculated using a paired t -test for parametric and Mann–Whitney U test for nonparametric continuous data and Chi-squared test for categorical data. Statistically significant p -values are indicated in bold.
