mean bias
(GEDVIfem - GEDVIjug)
GEDVIfem corrected by the correction formula
Diagnostic accuracy 67% 90% 88%
Sensitivity elevated GEDVIjug 100 100 100
Specificity elevated GEDVIjug 61 91 96
PPV elevated GEDVIjug 74 93 96
NPV elevated GEDVIjug 100 100 100
Sensitivity decreased GEDVIjug 31 100 81
Specificity decreased GEDVIjug 100 91 94
PPV decreased GEDVIjug 100 84 87
NPV decreased GEDVIjug 74 100 91
  1. Diagnostic accuracy, sensitivity, specificity, positive predictive value, negative predictive value for the prediction of jugular global end-diastolic volume based on uncorrected femoral global end-diastolic volume index, femoral global end-diastolic volume index corrected by subtraction of the mean bias and femoral global end-diastolic volume index corrected by the correction formula.
  2. GEDVIfem, femoral global end-diastolic volume index; GEDVIjug, jugular global end-diastolic volume index; PPV, positive predictive value; NPV, negative predictive value. Elevated GEDVI means GEDVI >800 mL/m2 and decreased GEDVI means GEDVI <680 mL/m2
