Values are presented as number (%), mean±standard deviation or median (range).

BP, blood pressure; HbA1c, hemoglobin A1C; HDL, high density lipoprotein; LDL, low density lipoprotein; FBS, fasting blood sugar; WBC, white blood cells; hs-CRP, high-sensitivity C-reactive protein.

aSmoking status are classified according to urinary cotinine levels of 50 ng/mL.

P-value were calculated by one-way ANOVA or Kruskal-Wallis test for continuous variables and chi-square test for categorical variables.
