BMI=weight/height2 ; SBP, systolic blood pressure; DBP, diastolic blood pressure; TG, triglyceride; TC, total cholesterol, HDL-C, high-density lipoprotein cholesterol; NGT, normal glucose tolerance; IFG, impaired fasting glucose; IGT, impaired glucose tolerance; IFG+IGT, IFG combined IGT; NDDM, newly-diagnosed diabetes mellitus.
Data are expressed as means ± SD.
X2 test was applied for the gender compositions among the groups. Additionally, the chi-square segmentation was used to adjust the significance level for multiple comparisons between the groups (a'=0.005).
One-Way ANOVA analysis was used for height, weight, TC and logarithmically transformed TG among the groups; LSD analysis was used both for TC and logarithmically transformed TG in the multiple comparisons between the groups.
Kruskal-Wallis H analysis was applied for age, BMI, waist circumference, SBP, DBP and HDL-C among the groups; Mann-Whitney U analysis was used for height, weight, age, BMI, waist circumference, SBP, DBP and HDL-C between the groups, and the Bonferroni correction was performed to adjust the significance level for multiple comparisons between groups (a'=0.005).
