Risk was predicted by the GRACE score only (A), by the GRACE score adjusted by NT-proBNP (B), or the GRACE score adjusted by GDF-15 (C). Hosmer-Lemeshow Chi‑square = 0.04 for GRACE score only (P = 0.98), Chi‑square = 0.24 for NT-proBNP–adjusted GRACE score (P = 0.89), Chi‑square = 0.44 for GDF-15–adjusted GRACE score (P = 0.80).
