  1. * P < 0.05 ** P < 0.01 vs. 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. FBG, fasting blood glucose; HDL, high density lipoprotein; LDL, low density lipoprotein; TC: Total cholesterol; TG: Triglyceride.
