LIV-4: A novel model for predicting transplant-free survival in critically ill cirrhotics

Table 5 Validation cohort: Comparison of the various scores and LIV-4

Score comparison	Validation cohort P value
MELD vs LIV-4	< 0.75
MELD-Na vs LIV-4	< 0.47
SOFA vs LIV-4	< 0.94
CLIF-SOFA vs LIV-4	< 0.27
RFH vs LIV-4	< 0.001
APACHE III vs LIV-4	< 0.074

Areas under the ROC curves were compared using De-Long’s method. MELD: Model for end-stage liver disease; Na: Sodium; SOFA: Sequential (or Sepsis-related) organ failure assessment; CLIF-SOFA: Chronic liver failure-sequential organ failure assessment; RFH: Royal Free Hospital; APACHE: Acute physiology and chronic health evaluation; ROC: Receiver operator characteristics.
