  • The displayed P values are based on the Wilcoxon rank-sum test comparing participants with a given NIAAA risk assessment versus those with the next lowest risk assessment. A test of independence between AUDIT scores and NIAAA risk assessment groups yielded a P value <.01. The analysis of variance test for trend yielded a P value <.01.
