Main finding
As reported in the abstract
Association of EEG metrics with cerebrovascular autoregulation
- Seizures, highly malignant patterns or burst suppression, alpha peak frequency and bispectral index associated with cerebrovascular autoregulation
- Other metrics: no or inconsistent associations
- Each specific combination of autoregulation and EEG metrics evaluated by at most 2 studies
- 67% adult, 59% critically ill
- 7 studies qualitative, 5 quantitative EEG metrics
