The male (OR, 1.632; 95% CI 1.224-1.983, p = 0.041), BMI (OR, 1.249; 95% CI 1.061-1.543, p < 0.001), NHHR (OR, 1.559; 95% CI 1.268–1.915, p<0.001), and AIP (OR, 1.349; 95% CI 1.146–1.843, p < 0.001) were identified as independent factors for OSA (Figure 4). Here, AIP is linked to obstructive sleep apnea syndrome.
