Preoperative controlling nutritional status as an optimal prognostic nutritional index to predict the outcome for colorectal cancer

Figure 1 The measurement of skeletal muscle area. A: The third lumbar vertebra on CT; B: The regions marked in red are the skeletal muscles, including the psoas major, paraspinal, transverse abdominis, external oblique, internal oblique, and rectus abdominis.

Figure 2 Kaplan-Meier curves for overall survival and replase-free survival. A and D: Controlling nutritional status high or low groups; B and E: pStageI-II patients; C and F: pStageⅢ patients. COUNT: Controlling nutritional status.

Figure 3 The time-dependent curves of controlling nutritional status, neutrophil-to-lymphocyte ratio, modified Glasgow prognostic score, and prognostic nutritional index. A: Predicting 3-year overall survival; B: Predicting 3-year replase-free survival. 95%CI: 95% confidence interval; AUC: Area under the receiver operating characteristics curve; COUNT: Controlling nutritional status; NLR: Neutrophil-to-lymphocyte ratio; mGPS: Modified Glasgow prognostic score; PNI: Prognostic nutritional index.

Figure 4 The time-dependent curves of controlling nutritional status + TNM stage and skeletal muscle mass index + TNM stage. A: Predicting 3-year overall survival; B: Predicting 3-year replase-free survival; C: The correlation between skeletal muscle mass index and controlling nutritional status. 95%CI: 95% confidence interval; AUC: Area under the receiver operating characteristics curve; COUNT: Controlling nutritional status; SMI: Skeletal muscle mass index.
