Table 6 Ability to predict the increase in mean arterial pressure ≥ 10% after infusion of 250 ml saline over 10 min

From: Changes in dynamic arterial elastance induced by volume expansion and vasopressor in the operating room: a prospective bicentre study

Variable Best threshold AUROC (95% CI) Sensitivity (95% CI) Specificity (95% CI) Youden Index J +LR −LR
Eadyn > 0.65 0.71 (0.57–0.82) 76 (53–92) 60 (42–76) 0.36 1.9 (1.2–3.1) 0.4 (0.2–0.9)

  1. The best threshold value was determined using Youden Index
  2. Youden Index J = Sensitivity + Specificity − 1
  3. AUROC area under receiver-operating characteristic curves, 95% CI 95% confidence interval, Eadyn dynamic arterial elastance, MAP mean arterial pressure, +LR positive likelihood ratio, −LR negative likelihood ratio
