Stepwise multiple regression model of adjusted urinary Sestrin2 levels in the OSA group (adjusted R² = 0.745)

	B (SE)	β	P values
Constant	−1.078 (0.525)		0.047*
AHI	0.033 (0.007)	0.420	< 0.001*
Oxygen saturation < 90% PRTS	0.094 (0.016)	0.509	< 0.001*
HDL	1.435 (0.444)	0.262	0.003*

Independent variables considered: age, gender, BMI, waist-to-hip ratio, neck circumference, AHI, lowest oxygen saturation, oxygen saturation < 90% PRTS, total sleep time, stage of rapid eye movement sleep, Epworth Sleepiness Score, triglycerides, total cholesterol, low-density lipoprotein, HDL, fasting blood glucose

AHI apnea/hypopnea index, PRTS percentage of recording time spent, HDL high-density lipoprotein

*P < 0.05, the results are statistically significant
