  1. sd standard deviation, GSS global symptoms score, n.s not significant
  2. aFor quantitative variables in a normal distribution, the Student’s t-test was used to compare groups of two or more classes; for variables that do not follow a normal distribution, the Wilcoxon signed-rank test or the Kruskal-Wallis test was used to compare groups of two or more classes. The value p < 0.05 was considered significant
