CONSORT diagram. A total of 263 patients were enrolled and 131 patients were randomized to the PDI-IVR system arm with usual care (UC) and 132 patients to the active-control arm with UC. Attrition was similar between the two arms, with 22 (16.7%) and 14 (10.7%) in the control and intervention arms, respectively, who did not complete the study (P = 0.16; χ2 test). If the 8 disqualified participants were excluded, the attrition was 15 (12%) and 13 (10%) in the control and intervention arms, respectively (P = 0.61; χ2 test). AHI = apnea-hypopnea index; CPAP = continuous positive airway pressure; PDI-IVR = peer-driven intervention with interactive voice response.
