When comparing OCD patients to healthy controls, we analyzed data from adult subjects (18 years and older) and pediatric/adolescent subjects (below 18 years), separately. For the purpose of basic comparisons of subcortical volume and cortical thickness and surface area, we pooled data from children (<12 years) and adolescents (12–17 years) in a pediatric/adolescent analysis (Boedhoe et al., 2017, 2018), but in the subsequent cross‐disorder comparisons with other child‐onset disorders (autism spectrum disorder, ASD) and attention deficit hyperactivity disorder (ADHD), we analyzed children and adolescents separately (Boedhoe et al., 2019).
