Figure 1: Consort diagram of participants randomized to the home-based versus hospital-based management pathways.

From: A randomized controlled trial of an ambulatory approach versus the hospital-based approach in managing suspected obstructive sleep apnea syndrome

Data were analysed on an intention-to-treat (ITT) basis comparing the two groups in terms of demographics, and waiting time for diagnostic tests, CPAP titration and treatment by including all patients randomized. Data were analysed on a modified ITT basis by including patients with AHI ≥ 15/hr starting fixed CPAP therapy in both groups whereas treatment per-protocol (TPP) analysis was conducted for those with AHI ≥ 15/hr who had completed the 3-month CPAP outcome study. * In group A with AHI ≥ 15/hr, 17 out of 86 patients failed the first home sleep test and had to undergo the second home sleep test which was successful. In group B with AHI ≥ 15/hr, 2 out of 86 patients had to undergo PSG twice. Seven out of 157 and 4 out of 159 in group A and group B “failed” sleep tests twice respectively due to either technical problems or poor sleep (total sleep time <0034 hrs) and the 7 patients in group A proceeded to PSG. # In group B, 25 patients refused to continue the study after randomization as the waiting time for polysomnography was too long.
