Abbreviations: HR, hazard ratio; CI, confidence interval; AFP, α-fetoprotein; DBIL, direct bilirubin; TACE, transarterial chemoembolization; KA, Kang’ai injection.

^aGroup: TACE + KA = 2, TACE = 1.

^bMaximum tumor size: 3.1-5.0 cm = 1, 5.1-10.0 cm = 2, ≥10.1 cm = 3.

^cAFP <200 ng/mL = 1, 200-1000 ng/mL = 2, >1000 ng/mL = 3.

^dTumor number: 1 tumor = 1, 2-3 tumors = 2, ≥4 tumors = 3.
