Fig. 2: Kaplan-Meier representation of medication adherence in both groups overtime.

The x-axis represents the follow-up months, and the y-axis represents the cumulative adherent patients’ proportion. Both app and control groups have shown an increase in cumulative adherent patients’ proportions over time. In the app and control groups, the median time for patients to become adherent was 2 and 3 months respectively. App group had a significantly higher cumulative adherent patients proportion compared to control group (P = 0.016).
