AIP and obstructive sleep apnea syndrome: Bikov et al. [7] found that mild, moderate, and severe OSA was associated with significantly higher AIP compared to control (controls: 53.35 [IQR 35.95 to 75.01], mild OSA: 75.15 [IQR 40.24 to 116.24], moderate OSA: 79.02 [IQR 49.68 to 109.60], and severe OSA: 101.16 [IQR 71.98 to 143.26]; P < 0.05 for comparing all severities with controls).
