Newcombe confidence intervals and McNemar asymptotic p values are based on paired data displayed in Supplemental Material Table S6
Psychiatric disorder includes both primary and additional diagnoses, based on only complete case (diagnostic assessment at both T1 and T2)
Comorbid psychiatric disorder includes all patients with more than one psychiatric disorder
aIn ADHD group there is 1 missing among girls
bRD is risk difference, the difference between the proportions of patients with psychiatric disorder or comorbid psychiatric disorder at T2 compared with T1
cn/ntotal means that there are (n) numbers of patients with psychiatric disorder among the total sample of patients
dn/ndisorder means that there are (n) numbers of patients with comorbid psychiatric disorder among the patients with the actual psychiatric disorder
en/ntotal means that there are (n) numbers of patients with comorbid psychiatric disorder among the total sample of patients
