The data are presented as the mean ± SD or number (percentage). Smoker: the patient's duration of smoking cessation exceeded three months, but the patient had smoked at least five cigarettes a day in the past two years or was a nonsmoker within three months. Drinker: drinks more than 4 drinks a day. FPG: fasting plasma glucose; TC: total cholesterol; TG: triglyceride; HDL-C: high-density lipoprotein cholesterol; LDL-C: low-density lipoprotein cholesterol. ∗ vs. grade I, p<0.05; # vs. grade II, p<0.05.
