Prognostic significance of rad-score for solitary HCC patients. a Training cohort: median TTR [95%CI] for low rad-score [n = 49] versus high rad-score [n = 163]: 38 [28.2–47.1] versus 53 [48.0–58.4] months; p = 0.005. b Validation cohort: p = 0.054. c Training cohort: median OS [95%CI] for low rad-score [n = 49] versus high rad-score [n = 163]: 54.9[45.4–64.5] versus 70.5 [66.6–74.5] months; p = 0.003. d Validation cohort: median OS [95%CI] for low rad-score [n = 37] versus high rad-score [n = 70]: 50.9[38.5–63.3] versus 82.2 [75.6–88.8] months; p = 0.003
