Hazard ratio (HR) for clinical outcomes in the AFP responder group compared with the AFP non-responder group.

Reference = AFP non-responder group
Abbreviations: OS = overall survival; PFS = progression-free survival; HR = hazard ratio; CI = confidence index; AFP = Alpha-fetoprotein;
aAdjusted age, gender, Child-Pugh class, performance status, Initial AFP (≤ 400 ng/mL vs. >), viral etiology, tumor size, sites of portal vein tumor thrombus, stage, and best radiologic response;
ball the possible variables (age, gender, Child-Pugh class, performance status, Initial AFP (≤ 400 ng/mL vs. >), viral etiology, tumor size, sites of portal vein tumor thrombus, stage) were included for the propensity score matching.
