Predicting coma and other low responsive patients outcome using event-related brain potentials: A meta-analysis
Abstract Objective A meta-analysis was performed to estimate the predictive power (odd ratio, OR) for awakening of auditory event-related potential (ERP) components in low responsive patients with stroke or hemorrhage, trauma, anoxic, post-operative, and metabolic encephalopathy etiologies. Methods...
