Figure 3 Hospitalization for heart failure-free survival curves of control subjects (bottom black line), patients with metabolic syndrome (middle black line), and diabetic patients (top black line). Normal patients: relative risk 1.00 (reference category); metabolic syndrome patients: relative risk 1.24, 95% confidence interval (CI) 0.86 to 1.79, p = 0.241; diabetic patients: relative risk 1.89, 95% CI 1.34 to 2.67, p = 0.0003. CHF = congestive heart failure. Methods as in Figure 1.
