  1. Only the indices with an AUROC >0.6 and p < 0.05 were included. Cutoffs estimated by Youden index
  2. NPV negative predictive value, ΔCDPV carotid peak velocity variation, SVV stroke volume variation, PLR Delta SVI rise in stroke volume index after passive leg elevation test, PPV pulse pressure variation
  3. aPositive predictive value
