Figure 6. Exploration of synergistic prognostic effect of PNI and SMI in CRLM patients. 3-month’s, 6-month’s and 12-month’s results were analyzed. The AUC of 3-month, 6-month and 12-month were 0.65, 0.85 and 0.80. PNI, prognostic nutrition index; SMI, skeletal muscle index; CRLM, colorectal cancer liver metastasis; AUC, area under curve.
