TTR and neoplasm: The nomogram was constructed based upon the following seven independent prognostic factors identified in the Cox model: TNM stage (I, II, or III), tumor site (caudate lobe, left, or right), tumor size (≤5 or >5 cm), tumor differentiation (low, high, or median), ALB (<28, 28–35 or ≥35 g/L), AST (≤40 or >40 IU/L), and TTR (≤12 or >12 months).
