Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and 95% confidence intervals (95% CI) for computed tomography (CT)-based estimations of central venous pressure (CVP CT) with regard to measured elevation of central venous pressure (CVP; CVP > 9 mmHg) are shown. CVP CT is separately shown for radiologist 1 (R1) and radiologist 2 (R2).
