Flow Diagram of the IDEATel Randomized Controlled Trial of Telemedicine. Abbreviations: CMS, Centers for Medicare and Medicaid Services; HPSA, Health Professionals Shortage Area; MUA, Medically Underserved Area. Dropped out refers to subjects who communicated that they wished to drop out of the study at some time during the follow-up period; some of these subjects returned for a follow-up examination. 1665 individuals were included in at least one of the analyses of the primary outcomes. A few participants did not provide any measures of a specific primary outcome and could not be included in the analyses of that outcome. The number of deaths in ▶ reflects deaths before dropout. An additional 124 participants died (usual care = 42, intervention = 82) after they dropped out of the study and were included in the intention-to-treat survival analyses.
