Legend: The AUROC for the OI ratio (dotted line) was 0.70 (95% CI 0.62–0.77). The AUROC for the model including the OI, IL-8, and TNF-R2 (gray line) was of 0.77 (95% CI 0.70–0.83). The AUROC for the expanded model including the OI, IL-6, IL-8, IL-10, TNF-R2, and HCT history (black line) was of 0.79 (95% CI 0.72–0.86). Chi-squared test for difference in ROC curves p=0.032.
