  1. #: Only the NR3C1 CpG units observed with a significant association of anxiety symptoms in the unadjusted model were reported here
  2. Model 1: MANCOVA demonstrated significant between-group difference after controlling for age, sex, BMI, cortisol, living arrangement, classmate relations, and teacher-classmate relations
  3. Model 2: MANCOVA demonstrated significant between-group difference after controlling for age, sex, BMI, cortisol, living arrangement, classmate relations, teacher-classmate relations, and academic pressure
  4. *: Statistical significance was set at P < 0.025 after Bonferroni correction for 2 CpG sites
