  1. The average values were presented as mean ± SD or median (IQR), as appropriate. Four groups were compared with ANOVA or Kruskal-Wallis test (*) for continuous variables, and chi-square test for categorical data (#). Statistically significant differences between groups (p-values < 0.05) were bolded
