Notes: aNo statistics computed because all cases were censored in one stratum (Asian). bExcluded patients without biopsy: TARE_alone (n=22) and TARE_sorafenib (n=20). cExcluded patients with ECOG ≥2: TARE_alone, ECOG 2 (n=2) and ECOG 3 (n=1); TARE_sorafenib, ECOG 2 (n=2). dExcluded patients with BCLC A (n=5) and BCLC D (n=1) in TARE_alone subgroup.
