Logistic regression analysis showing the independent predictors of true silent myocardial ischemia in diabetic subjects

Variable	Odds ratio [95% CI]	p
Male gender (no/yes)	3.3 [1.2-8.5]	0.02
Diabetic retinopathy (no/yes)	11.7 [3.7-37]	0.03
Age (years)	1.03 [0.8-1.28]	0.79
HbA1C (%)	0.67 [-0.42-1.76]	0.57
Diabetes duration (years)	0.82 [0.59-1.05]	0.08
Plama cholesterol (mg/dl)	1.01 [0.98-1.04]	0.44
Smoking habit (no/yes)	0.20 [-3.01-3.41]	0.79

Apart from the variables associated with true silent ischemia in univariate analysis (gender, diabetic retinopathy), HbA1c, diabetes duration, and classic cardiovascular risk factors (age, plasma cholesterol, hypertension and smoking habit) were also entered in the logistic regression analysis.
