Dynamic nomogram predicts sepsis risk in patients with acute liver failure: Analysis of intensive care database with external validation

Figure 3 Receiver operating characteristic and calibration curves to assess the accuracy and calibration of sepsis in the acute liver failure model. A: Receiver operating characteristic (ROC) comparison for sepsis risk in the internal derivation cohort; B: ROC comparison in the internal validation cohort; C: ROC comparison in the external validation cohort; D: The calibration curve of the internal derivation cohort; E: The calibration curve of the internal validation cohort; F: The calibration curve of the external validation cohort. SOFA: Sequential Organ Failure Assessment; SIRS: Systemic inflammatory response syndrome; SIALF: Sepsis in acute liver failure.
