  Fig. 2. Correlations among EATV, EATA, FAI, OSA severity, AHI, LSaO2, MSaO2, and T90. EATV epicardial adipose tissue volume, EATA epicardial adipose tissue attenuation, FAI pericoronary fat attenuation index, AHI apnea–hypopnea index, lowest SaO2 lowest oxygen saturation at night, mean SaO2 average transcutaneous oxygen saturation at night, T90 total sleep time spent with arterial oxygen saturation < 90%

  Fig. 3. Correlations among the CVAI score, OSA severity, AHI, LSaO2, MSaO2, and T90. CVAI Chinese visceral adiposity index, AHI apnea‒hypopnea index, lowest SaO2 lowest oxygen saturation at night, mean SaO2 average transcutaneous oxygen saturation at night, T90 total sleep time spent with arterial oxygen saturation < 90%
