Table 2 Predictive values of EEG patterns

From: Early EEG for outcome prediction of postanoxic coma: prospective cohort study with cost-minimization analysis

Favorable or unfavorable pattern

Time since cardiac arrest

Predicted outcome

Specificity (95% CI)

Sensitivity (95% CI)

PPV (95% CI)

NPV (95% CI)

Favorable EEG pattern

12 h

Good

88% (81‒93)

51% (42‒60)

81% (70‒88)

65% (57‒72)

Unfavorable EEG pattern

24 h

Poor

100% (98‒100)

29% (22‒-36)

100% (93‒100)

58% (52‒64)

  1. EEG electroencephalography, Favorable EEG continuous pattern, diffusely slowed or normal, Unfavorable EEG isoelectric, low-voltage, or burst-suppression with identical bursts, PPV positive predictive value indicating the probability that patients with a positive test result truly have the predicted outcome (a PPV of 100% therefore indicates 0% false positives), NPV negative predictive value indicating the probability that patients with a negative test result truly do not have the predicted outcome, CI confidence interval
