To compare mortality across encephalopathy subtypes—delirium, toxic, metabolic, and unspecified—in ICU patients and assess independent predictors of survival using adjusted and subgroup analyses. Additionally, to explore whether the lower mortality in delirium reflects its greater reversibility compared with other encephalopathy etiologies.
