^aAOR = adjusted odds ratio

^bCI = 95% confidence interval

^cAge, ethnicity, public assistance, not living with both biological parents, parental drug/alcohol problems, and site were controlled for in this set of analyses

^dReference group

^eA p value for gender difference is listed here if the AORs for boys and girls, for the specified type of mental disorder, were found to be significantly different, using the Wald test for equality of coefficients; NS = not significant

^fAge, ethnicity, public assistance, not living with both biological parents, parental drug/alcohol problems, site and depressive disorder were controlled for in this set of analyses
