From: Clinical features and predictors of metabolic syndrome among obstructive sleep apnea patients

	Area under the curve	P value	95% confidence interval
	Area under the curve	P value	Lower bound	Upper bound	Cut-off	Sensitivity %	Specificity %
BMI in kg/m²	0.769	< 0.001	0.662	0.877	38	84.9	66.7
Waist circumference(cm)	0.739	< 0.001	0.623	0.855	134	56.6	85.2

Hip circumference (cm)	0.666	0.006	0.546	0.785	142	50.9	88.9
Average oxygen saturation (%)	0.380	0.056	0.257	0.503	–	–	–
SPO2 time < 90% (%)	0.646	0.024	0.519	0.772	23	54.7	74.1

BMI boy mass index, SPO2 O2 saturation in the peripheral blood, ROC curve was constructed with area under curve analysis, best cut-off value was chosen according to the highest Youden index. p value is considered significant if below 0.05
