- Comparing the age, gender, FBG and Serum Lipid/Lipoprotein between subjects with smoking and non-smoking habit, and among groups with different smoking quantity, Using χ2 or Fisher’s exact test (wherea an expected cell count was < 5) for categorical variables and unpaired Student’s t test for continuous variables. In the testing, a P value < 0.05 was considered to be statistically significant. * P < 0.05 ** P < 0.01. FBG, fasting blood glucose; HDL, high density lipoprotein; LDL, low density lipoprotein; TC: Total cholesterol; TG: Triglyceride.
