Bold typeface signifies significant results.
†Indicates relative risk ratios (RRR) rather than ORs.
*All models were adjusted for clustering at the school level, and adjusted for age, sex, ethnicity and SES—model 1 comprises the foster care variable, model 2 comprises the foster care variable and all relationship variables.
