Iinter-hemispheric coherence values were ANOVA; Post hoc comparisons were carried out using Bonferroni correction; Data are presented as mean (SD); Bold font indicates statistically significant group differences.
ADHD = attention deficit hyperactivity disorder, IGD = internet gaming disorder, ADHD+IGD = ADHD comorbid with IGD group, ADHD-only = ADHD without comorbidity group, HC = healthy control group, ANOVA = analysis of variance, SD = standard deviation.
