Cardiac arrest & resuscitation
Benign EEG for prognostication of favorable outcome after cardiac arrest: A reappraisal
Authors' conclusion
The modified "benign EEG" classification demonstrated a markedly higher sensitivity towards favorable outcome, with minor impact on PPV.
Study context
- Population
- Unconscious adults after cardiac arrest (CA), EEG within 72 h (registry 1.2018–8.2021)
- Participants
- 381 adults
- Exposure
- Modified "benign EEG" vs Westhall's "benign EEG"
- Outcome
- Predictive performance for good outcome (Cerebral Performance Category 1-2)
- Follow-up
- 3 months
Methodological detailsregistry, diagnostic accuracy comparison
