Figure 3. Mediation analyses of iron status and risks of mortality and heart failure.

Figure 3.

Results for the iron groups are reported as hazard ratios and 95% confidence intervals compared to the iron replete group. For the continuous variables, results are reported as hazard ratios per 1 standard deviation of natural log FGF23, hemoglobin, and natural log PTH. The full model was stratified by center, adjusted for age, sex, race, ethnicity, diabetes, smoking, systolic blood pressure, body mass index, prior cardiovascular disease, eGFR, urine albumin-to-creatinine ratio, and erythropoietin use.

Abbreviations: eGFR, estimated glomerular filtration rate; FGF23, fibroblast growth factor 23; Hgb, hemoglobin; PTH, parathyroid hormone
