Kaplan–Meier curves of overall survival (OS) (A) and progression-free survival (PFS) (B) according to α-fetoprotein (AFP) response. Patients with an AFP response had significantly longer OS and PFS than patients without an AFP response (median 10.9 versus 5.2 months, log-rank test P=0.001 for OS and 5.3 versus 2.9 months, log-rank test P<0.001 for PFS).
Abbreviation: vs, versus.
