- Logistic regression techniques used a backwards conditional model. This method also controlled for local authority of school (n = 21). Local Authority AORs have not been displayed due to space but were significant for all outcome measures. § drinking frequently = >1 session/week; drinking heavily = drink ≥5 drinks/session ≥1 per month. ^IMD = Index of multiple deprivation. AOR = Adjusted Odds Ratio. Ref = Reference category. 95% CI = 95% confidence intervals. ns = Not significant. Reported P values are * <0.05 ** <0.01 *** <0.001. Comparator groups for dependent variables in unsupervised consumption and access are, respectively, drinkers who do not: typically drink unsupervised inside; typically drink outside (in streets, parks and shops); buy their own alcohol; take alcohol from their parents without permission or; proxy purchase. For frequent drinking the reference group is drinkers who do not drink >1 session/week and for heavy drinking, drinkers who do not drink ≥5 drinks/session ≥1 per month.
