(A) Kaplan-Meyer survival curves for 398 myeloma patients separated by HGF high (≥1.10 ng/mL, n = 174; ○) versus low (<1.10 ng/mL, n = 224; ◊). The survival difference was significant (P = .02). (B) Kaplan Meyer survival curves for 25 myeloma patients with extremely high pretreatment values of HGF (≥3.00 ng/mL; ○) and for 224 patients with low pretreatment values (<1.10 ng/mL; ◊). The survival difference was significant (P = .001).
