Analysis of aggressiveness factors in hepatocellular carcinoma patients undergoing transarterial chemoembolization

Figure 1 Kaplan-Meier survival plots between categories of aggressiveness Index, in total cohort. Aggressiveness index as sum of scores, MTD (in tertiles): MTD < 4.5; 4.5 ≤ MTD ≤ 9.6; MTD > 9.6; scores 1, 2, 3 respectively; AFP (cut-off): AFP < 100; 100 ≤ AFP ≤ 1000; AFP > 1000 ng/mL; scores 1, 2, 3 respectively; PVT (no/yes): PVT (no); PVT (yes); scores 1, 3 respectively; Tumor nodules (number): Nodules ≤ 3; nodules > 3; scores 1, 3 respectively. ¹Wilcoxon (breslow) test. MTD: Maximum tumor diameter; AFP: Alpha-fetoprotein; PVT: Portal vein thrombosis.
