* For categorical variables Chi-square test was used to access the dependence of variables; effect size measures (Phi or Cramer’s V to 2 × 2 comparations or more, respectively) and p-value are reported. For scale variables, Mann-Whitney test was employed; effect size measure (r) and p-value are reported.
