  1. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) given as percentages with 95% confidence intervals (95% CI) in parentheses for computed tomography (CT)-based estimations of global end-diastolic volume index (GEDVI) with regard to GEDVI derived from transpulmonary thermodilution (TPTD) are shown separately for radiologist 1 and radiologist 2.
