  1. Categorical variables are analyzed by Chi-Square test. Continuous variables are analyzed by ANOVA. Post-hoc comparisons were done by Bonferroni correction. Non-parametric variables were analyzed by Kruskal–Wallis test. Post-hoc comparisons were done by Dunn’s test.
  2. aP < 0.05 Resilient versus Concordant
  3. bP < 0.05 Resilient versus Uncoupled
  4. cP < 0.05 Concordant versus Uncoupled
