Table 2. Associations between serum hs-CRP and the prevalence of type 2 diabetes.

	Serum hs-CRP			P for trend
	Q1 + Q2 (≤0.31 mg/L)	Q3 (>0.31∼0.66 mg/L)	Q4 (>0.66 mg/L)
	OR (95% CI)	OR (95% CI)	OR (95% CI)
Prevalence rate of diabetes (%)	3.0	6.4	10.2
Model 1	1	1.7 (0.86, 3.5)	3.0 (1.6, 5.7)	<0.001
Model 2	1	1.9 (0.91, 3.8)	3.2 (1.7, 6.3)	<0.001
Model 3	1	1.5 (0.68, 3.1)	2.4 (1.2, 4.8)	0.015
Model 4	1	1.5 (0.71, 3.3)	2.4 (1.2, 4.9)	0.016

hs-CRP, high-sensitivity C-reactive protein; Q2, first quartile; Q3, second quartile; Q4, third quartile; Q1, fourth quartile.

OR, odds ratio; CI, confidence interval.

Model 1: adjusted for age and sex.

Model 2: adjusted for age, sex, recruit group, smoking status, current alcohol drinkings, leisure-time exercise, carbohydrate intake, and energy intake.

Model 3: adjusted for the covariates in model 2 plus body mass index.

Model 4: adjusted for the covariates in model 3 plus family history of diabetes.
