Preoperative immunonutrition status predicts survival after colorectal cancer resection: Nomogram based on modified systemic inflammation score

Figure 3 Kaplan-Meier overall survival curves. A and B: Curves stratified by serum albumin and neutrophil-to-lymphocyte ratio (NLR) in colorectal cancer; A: Overall survival curves for patients in the low-albumin and high-albumin groups; B: Overall survival curves for patients in the low-NLR and high-NLR groups. Shaded areas represent 95% confidence intervals. The numbers of patients at risk at each time point are shown below the plots. P values were calculated using the log-rank test (both P < 0.0001); C and D: Curves stratified by the modified systemic inflammation score; C: Overall survival curves for patients with modified systemic inflammation score (mSIS) scores of 0, 1, and 2; D: Overall survival curves for patients with mSIS = 0 and mSIS ≥ 1. Shaded areas represent 95% confidence interval. The numbers of patients at risk at each time point are shown below the plots. P values were calculated using the log-rank test (both P < 0.0001). mSIS: Modified systemic inflammation score; NLR: Neutrophil-to-lymphocyte ratio.
