Table 2. Odd Ratios (OR) and 95% CI for Insulin Variables and CHD From Multiple Logistic Regression Analyses: the Rancho Bernardo Study, 1992-1996.

Variable*	OR	95% Cl	P
Men
Fasting Insulin	0.85	0.56-1.31	0.46
Postchallenge Insulin	1.17	0.83-1.66	0.36
Proinsulin	2.41	1.42-4.11	0.001
C-peptide	1.07	0.61-1.88	0.82
Women
Fasting Insulin	1.25	0.89-1.76	0.20
Postchallenge Insulin	1.44	1.06-1.96	0.02
Proinsulin	1.80	1.22-2.64	0.003
C-peptide	1.32	0.88-1.97	0.18

Covariates were age, BMI (body mass index), systolic blood pressure, HDL (high-density lipoprotein) cholesterol, and current estrogen use (women).

^*The log-odds for CHD increase for every 1-unit increase in the independent variable. confidence interval (CI); coronary heart disease (CHD)
