Table 3.

Change of near-term notification effect over time.

Notification typea	Relative risk on the first day after download (95% CI)	Multiplicative change in effect (95% CI)
Pooled notifications (both standard and new)	3.849 (2.811-5.270)	0.993 (0.975-1.012)
Standard notification	4.193 (3.004-5.854)	0.989 (0.970-1.001)
New notification	3.534 (2.536-4.924)	0.997 (0.976-1.017)

^aMultiplicative change in relative risk per day since download. Adjusted for the continuous variables of age, Alcohol Use Disorders Identification Test score, days since download, the categorical variables of sex and employment type, and the time-varying variables “Did the use user the app before 8 PM that day?” and “Did the users use the app after 9 PM the day before?”
