Figure 2. ROC curves for baseline SMI (A) and PNI (B) were constructed, AUC for SMI and PNI were separately 0.69 and 0.57; prognostic value of SMI in PFS (C) and OS (D) was also determined in CRLM patients, Patients with initial low SMI were found to have significantly shorter duration of PFS (P=0.002) and OS (P-value<0.001). ROC, receive operating curve; AUC, area under curve; SMI, skeletal muscle index; PNI, prognostic nutrition index; PFS, progression free survival; OS, overall survival.
