Data were analyzed using binary logistic regression. Model 1: Crude model; Model 2: adjust for age; Model 3: adjust for age, sex; Model 4: adjust for age, sex, BMI. Statistical significance was defined at P < 0.05. mtDNAcn: Mitochondrial DNA copy number; ROS: Reactive Oxygen Species; OR: odds ratio; CI: confidence interval.
