  1. Data in parentheses are numerators/denominators; data in brackets are the 95% confidence intervals. AUC of the combined c and φ was obtained by using probabilities estimated from logistic regression. AUC values were compared using the Delong test with respect to an AUC value of c
  2. ICG-R15: 15-min indocyanine green retention rate, AUROC: area under receiver operating curve
