Moderate deficiency (10–20) showed a strong trend toward worse OS that narrowly missed significance. Liver metastasis was independently associated with significantly worse OS (adjusted HR 1.42, 95% CI 1.06–1.91, p = 0.02), consistent with published literature where HRs for liver metastasis typically range from 1.4 to 2.0.
