Kaplan–Meier analyses of cardiovascular events, that is, rehospitalization and cardiovascular death, in the above-/equal- and below-median BNP levels (a) and FGF23 levels (b), and the combination of BNP and FGF23 levels (c). The serum FGF23 levels predicted the incidence of cardiovascular death and/or hospitalization owing to HF, and the plasma BNP levels predicted these same clinical outcomes. The most potent predictor of cardiovascular outcomes was the combination of BNP and FGF23 levels in (c). BNP, B-type natriuretic peptide; FGF23, fibroblast growth factor 23; HF, heart failure.
