  1. Abbreviations: ADHD Attention-deficit/hyperactivity disorder, ASD Autism spectrum disorder. Values are presented as absolute numbers (percentage of cases/controls). All p-values were calculated for each case group against the control group from Chi-squared test. * P < .05, ** P < .01 and *** P < .001. Case-groups comparisons column indicates between which case-groups were found statistically significant differences (a: ADHD, b: ASD, c: Co-occurrence), and its magnitude
