Table 1 Risk Assessment for early Mortality (RAM)a score for hepatectomy for hepatocellular carcinoma

From: RAM score is an effective predictor for early mortality and recurrence after hepatectomy for hepatocellular carcinoma

  1. aRisk Assessment for early Mortality score
  2. bthe regression coefficients (B) were multiplied by two and rounded to integer in order to calculate the RAM score
  3. cincludes tri-segmentectomy, right/left lobectomy, and extended right/left lobectomy
  4. dmajor surgical complications include grade III-IV surgical complications
  5. eAUC = 0.723, P < 0.001. When Cutoff score is 4.5, the sensitivity and specificity for 6-month mortality was 0.717 and 0.644, respectively
