Minimum O2 saturation	0.92 (0.86, 0.98)	0.006
Stage 3–4, % time	0.97 (0.94, 1.00)	0.085
Sleep efficiency	0.94 (0.90, 0.97)	< 0.001

Definition of abbreviations: AHI = apnea–hypopnea index; CI = confidence interval; OR = odds ratio.

Each OR is adjusted for age, sex, race, and preterm status, and derived by separate logistic regression models.
