Site comparison excluding CAI > 5.0 during PAP titration grouping (no significant differences)

Altitude, meters (Site)	Excluding CAI > 5.0 - N	Excluding CAI > 5.0 titration adequacy (SD)	Excluding CAI > 5.0 repeat titrations
1421 (1)	133	1.36 (0.77)	1 (0.7%)
1808 (2)	114	1.35 (0.72)	4 (3.5%)
2165 (3)	85	1.39 (0.66)	3 (3.5%)

Titration quality rating: 1-optimal (AHI < 5.0 with supine Stage R), 2-good (AHI < 10.0 with supine Stage R), 3-adequate (AHI < 15.0 or without supine Stage R), or 4-unacceptable (AHI > 15.0)
