Note. Models were based on 308 persons and 1,767 SAM use days. Model 1 does not control for alcohol use, while Model 2 does control for alcohol use (Level 1 = number of drinks consumed that day; Level 2 = average number of drinks per day). RR = Rate Ratio; CI = Confidence Interval. PM report refers to afternoon survey.
