Comparison of variables between non-smoking group and smoking group.

Values are presented as mean ± SD. P-values were from independent t-test. BMI was calculated from body weight (kg)/height (m²). Fat mass was analyzed by bio-impedance analysis. Alcohol: average alcohol consumption in a week.

BMI: body mass index, WC: waist circumference, SBP: systolic blood pressure, DBP: diastolic blood pressure, oxLDL: oxidized low density lipoprotein, ICAM-1: inter-cellular adhesion molecule-1, IL-6: interleukin-6, ECO_0min: concentration of expiratory CO before cigarette smoking detected by micro smokerlyzer, ECO_5min: concentration of expiratory CO after 5 minutes of cigarette smoking detected by micro smokerlyzer, ECO_30min: concentration of expiratory CO after 30 minutes cigarette smoking detected by micro smokerlyzer, NCV_0min: nailfold capillary blood velocity before smoking, NCV_5min: nailfold capillary blood velocity after 5 minutes of cigarette smoking, NCV_30min: nailfold capillary blood velocity after 30 minutes of cigarette smoking.

^*Marked on the P-values with significance after age, WC, ExpCO-1, ExpCO-2, and ExpCO-3 adjustment by analysis of covariance test.
