*The fourth quartiles were shown with the first quartile as the referenced group. Model 1 adjusted for age, gender, and BMI. Model 2 adjusted for age, gender, BMI, hypertension, dyslipidemia, eGFR, and diabetes mellitus.
OR, odds ratio; minSpO2, minimal oxygen saturation; RE, respiratory event; NRE, non-respiratory events; TP, total power; SDNN, standard deviation of NN interval; LF, low-frequency; HRV, heart rate variability.
