  4. cDuration of survival not specified. Additionally, survival only reported for those with good neurological outcome defined as Glasgow–Pittsburgh cerebral performance categories (CPC) 1 and 2. CPC 1 indicates good capability, CPC 2 indicates slight disability, CPC 3 indicates severe disability, CPC 4 indicates coma or vegetative state, CPC 5 indicates cerebral death. CPC score of 1 or 2 was considered favorable, while a score of 3, 4, or 5 indicated an unfavorable functional neurological outcome
