All sex hormones are log-transformed and standardized. Hazard Ratios are associated with 1 SD decrease in log sex hormones (total T: 0.51 nmoI/L; DHEA-S: 0.61 µg/dL; SHBG: 0.47 nmoI/L). Bolded results are statistically significant.
Abbreviations: HF, heart failure; HFpEF, heart failure with preserved ejection fraction; HFrEF, heart failure with reduced ejection fraction; IR, incidence rates; T, testosterone; DHEA-S, dehydroepiandrosterone sulfate; SHBG, sex hormone binding globulin.
a Model 1 (demographics): adjusts for age and race center groups.
b Model 2 (+lifestyle factors): model 1 + education, waist-to-hip ratio, physical activity, and smoking.
c Model 3 (+CVD risk factors): model 2 + systolic blood pressure, use of antihypertensive medications, total cholesterol, HDL-C, use of lipid lowering medications, diabetes, eGFR, and prevalent CHD.
