Fig. 2

The adjusted R2 from trial calendar day 31 to 279 (March 13, 2021–December 19, 2021) is plotted from each day’s model. We calculated adjusted R2 from the proportion of variance in daily adherence that is explained by the five intervention factors in the reinforcement learning model. We selected those windows as they each had a minimum of 5 patient observations that day.
