Pearson’s correlation coefficient between each mitochondrial respiratory parameter and cardiometabolic risk factor. Abbreviations: SBP, systolic blood pressure; DBP, diastolic blood pressure; BMI, body mass index; TC, total cholesterol; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; ATP_O2, ATP-linked oxygen consumption. α was set at P < 0.05 (significant associations indicated by boldface).
