Table 3. Multivariate logistic analysis of the risk factors for 2-h NDM (n = 1197).

	OR (95% CI)	P
Forced variables
Age, years	1.63 (1.14–2.30)	0.007
HbA1c, %	1.89 (1.44–2.48)	<0.001
FPG, mg/dl	1.70 (1.28–2.25)	<0.001
Selected
SUA, mg/dl	1.36(1.09–1.99)	0.03

Multivariate stepwise logistic regression was performed to determine the influential factors of 2-h NDM (0, 1), in which age, FPG and HbA1C were forced in the model and gender, smoking and drinking, BMI, SBP, DBP, total cholesterol, HDL and LDL, triglycerides, SUA, log-CRP and e-GFR were considered as potential influential factors. OR (odds ration) and 95% CI (confidence interval) was calculated per 10 years in age and per 1-SD in other quantitative variables and presence against absence in qualitative variables. Only significant influential factors were shown in the table. 2-h NDM, 2-h newly diabetes mellitus; BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; FPG, fasting plasma glucose; HDL, high density lipoprotein; LDL, low density lipoprotein; SUA, serum uric acid; log-CRP, logarithmic transformed C-reactive protein; e-GFR, estimated glomerular filtration rate. International system of units (SI) conversion: plasma glucose 1 mg/dl = 1/18 mmol/l; SUA 1 mg/dl = 59.5 µmol/l.
