Line graph comparing UHC Service Coverage Index against Digital Health Adoption Index for four categories: Rapid Adopters (red), Slow Adopters (blue), Digital-First (green), and UHC-First (purple). Each line shows increasing UHC coverage with higher digital health adoption, with Rapid Adopters performing best. A vertical dashed line at Adoption Threshold marks a key transition point on the x-axis.
