Fig. 3: Feasibility of the digital medication system.

This figure presents the feasibility scores of the digital medication system, as reported by health workers (a), caregivers (b), and patients (c) in the intervention group, measured at 3 months, 6 months, and 12 months. Each evaluation criterion is represented by a distinct color: blue for acceptability of the intervention, red for the likelihood of recommending the intervention, and green for satisfaction with the intervention’s performance. Data for each visit are represented by bars, with the y-axis indicating the feasibility score (range: 0–10).
