Variables that fit a normal distribution were expressed as mean ± SD. Variables that did not fit a normal distribution were expressed as median (interquartile range). BMI: body mass index, DBP: diastolic blood pressure, HDL-C: high-density lipoprotein cholesterol, IASBPD: inter-arm systolic blood pressure difference, IADBPD: inter-arm diastolic blood pressure difference, LDL-C: low-density lipoprotein cholesterol, SBP: systolic blood pressure, TC: total cholesterol.
