a
Number of participants available for analysis.
b
Total number of follow-up observations.
c
Incidence rate ratio estimated by mixed-effects negative binomial regression. Models included indicator variables for month of assessment and the baseline value of the outcome being evaluated.
d
Confidence interval estimates and tests of significance were based on the robust variance estimator (Rosenblum and van der Laan, 2009).
e

f
Excludes observations for which participants reported zero drinking days during assessment period.
