Note. CI = confidence interval; p = p-value for trend
a
Lifetime abstention: <12 drinks in lifetime.
b
Years = range of years covered by trend and {%} = prevalence (or percentage) corresponding to the initial and last years covered by the trend.
c
AAPC is presented for overall trends that include all joinpoint segments. APC is presented for single segments calculated by joinpoint. When there are no joinpoints, AAPC=APC.
