^aAOR = adjusted odds ratio

^bCI = 95% Confidence interval

^cControlling for age, ethnicity, public assistance, not living with both biological parents, parental drug/alcohol problems and site

^dNo estimates available because of empty cells (no boy had co-occurring agoraphobia and smoking)

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

^fIn addition to the variables controlled for in model 1, depressive disorders were also controlled for here

⁺p < 0.10;

^*p < 0.05;

^**p < 0.01;
