Ninety five percent confidence intervals in parentheses, ADHD attention deficit hyperactivity disorder, CD conduct disorder, ODD oppositional defiant disorder, Any Anx any anxiety disorder, Any Dep any depressive disorder, OR Odds Ratio. Adjusted ORs for column 4 were derived from a logistic regression model that included all disorders as predictors.

Unadjusted odds ratio in community is different from unadjusted OR in clinic, p<0.01.
