Note. All models adjusted for gender, race/ethnicity, and grade in school and used Generalized Estimating Equations (GEE) to adjust for clustering of students within schools; we coded outside- and within-school adult support variables as 0 for 'no/not sure' and 1 for 'yes';
OR = odds ratio; CI = confidence interval;
