The association between RC and T2D in logistic analysis model

	Model 1	Model 2	Model 2
	OR (95% CI)	OR (95% CI)	OR (95% CI)
Quartile 1	Reference	Reference	Reference
Quartile 2	1.26 [1.13, 1.41]	1.10 [0.98, 1.24]	1.07 [0.90, 1.27]
Quartile 3	1.97 [1.78, 2.19]	1.58 [1.41, 1.76]	1.19 [1.00, 1.41]
Quartile 4	2.58 [2.33, 2.86]	2.16 [1.94, 2.41]	1.24 [1.03, 1.50]
RC	2.37 [2.18, 2.58]	2.21 [2.02, 2.43]	1.23 [1.02, 1.49]

Models were derived from binary logistic regression analysis. Model 1: unadjusted. Model 2: adjusted for age, sex, ethnicity. Model 3: adjusted for age, sex, ethnicity, DBP, heart rate, BMI, HOMA-IR, TC, LDL-C, creatinine, blood nitrogen urea, AST, FBG, sodium, potassium. Abbreviations: DBP, diastolic blood pressure; BMI, body mass index; HOMA-IR, homeostasis model assessment of insulin resistance; TC, total cholesterol; LDL-C, low-density lipoprotein cholesterol; AST, aspartate aminotransferase; FBG, fasting blood glucose, OR, odds ratio; CI, confidence interval
