Abbreviation: ND, neurologic deterioration.
Several patients deteriorated by >1 etiology. Patients with >1 etiology of ND who experienced a nonreversible cause of ND were classified as having nonreversible ND and not categorized as having a reversible ND in the analysis comparing reversible versus nonreversible ND.
*
Percentages described are reported as the number of patients having a certain stroke etiology who experienced ND divided by the total number of patients with the respectful stroke etiology.
