The association between RC and IR in logistic analysis model

	Model 1	Model 2	Model 3
	OR (95% CI)	OR (95% CI)	OR (95% CI)
Quartile 1	Reference	Reference	Reference
Quartile 2	1.46 [1.35, 1.58]	1.51 [1.40, 1.63]	1.20 [1.09, 1.33]
Quartile 3	2.31 [2.14, 2.49]	2.42 [2.24, 2.62]	1.45 [1.31, 1.62]
Quartile 4	4.29 [3.98, 4.63]	4.60 [4.25, 4.99]	1.65 [1.41, 1.94]
RC	4.50 [4.16, 4.86]	4.17 [3.85, 4.51]	1.53 [1.22, 1.93]

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, education levels, hypertension, self-reported of diabetes, hypercholesterolemia, chronic pulmonary disease, heartrate, BMI, TG, TC, LDL-C, creatinine, ALT, AST, FBG, uric acid, sodium. Abbreviations: RC, remnant cholesterol; IR, insulin resistance; T2D, type 2 diabetes; BMI, body mass index; TG, triglycerides; TC, total cholesterol; LDL-C, low-density lipoprotein cholesterol; ALT, alanine aminotransferase; AST, aspartate aminotransferase; FBG, fasting blood glucose; OR, odds ratio; CI, confidence interval
