Distribution of radiographically estimated values of global end-diastolic volume index (GEDVI), extravascular lung water index (EVLWI), and central venous pressure (CVP) according to the used thresholds. Data are presented as absolute numbers (n) with percentages in parentheses. CT, computed tomography; R1, radiologist 1; R2, radiologist 2.
