Relationship among Insulin Therapy, Insulin Resistance, and Severe Coronary Artery Disease in Type 2 Diabetes Mellitus

Table 2

Binary logistic regression coefficients for association between NITDM or ITDM with severe CAD and without CAD.

Variables^†	NITDM with severe CAD and without CAD			Variables^†	ITDM with severe CAD and without CAD
	Odds ratios	95%CI	value		Odds ratios	95%CI	value
Hypertension	1.600	1.025–2.500	0.039	Hypertension	1.624	1.094–2.411	0.016
Fasting C peptide (ng/mL)	1.216	1.011–1.462	0.038	Body mass index (kg/m^2)	1.104	1.051–1.159	<0.001
Age (years)	1.042	1.021–1.063	<0.001	Age (years)	1.060	1.040–1.079	<0.001
Fasting insulin (μU/mL)	1.028	0.999–1.057	0.056

^† Age, hypertension, body mass index, duration of diabetes, fasting insulin and fasting C peptide are analyzed in the multivariate model, and those in the equation in multiple model are shown in the table. CAD, coronary artery disease; CI, confidence interval; NITDM, non-insulin-treated diabetes mellitus, ITDM, insulin-treated diabetes mellitus.
