Multivariate linear regression analysis between different OSA severity measures and hs‐CRP value adjusting for significant variables from correlation analysis

Variables	β regression coefficients	P‐value
AHI (events/h)	.084	.152
ODI	.076	.202
Longest apnea/hypopnea time (s)	.078	.181
Lowest SaO2 (%)	−.159	.004
Mean SaO2 (%)	.001	.984
TST with SaO2 < 90% (%)	.069	.220

Note: Significant variables from correlation analysis were adjusted in multivariate linear regression including age, BMI, hypertension, hyperlipidemia, LVEDD, fasting blood sugar, and supine time.

Abbreviations: AHI, apnea hypopnea index; BMI, body mass index; Hs‐CRP, high‐sensitivity C‐reactive protein; LVEDD, left ventricular end‐diastolic dimension; OSA, obstructive sleep apnea; ODI, oxygen desaturation index; SaO₂, oxygen saturation; TST, total sleep time.
