Hazard ratios were adjusted for parental psychiatric history, maternal characteristics (parity, age at birth, highest educational level, cohabitation with a partner, residence, and birth country), and birth characteristics (adult’s sex, calendar year of birth). Markers represent estimates, with horizontal lines indicating 95% CIs. ADHD indicates attention-deficit/hyperactivity disorder; OCD, obsessive-compulsive disorder; ODD/CD, oppositional defiant disorder/conduct disorder.
