    Outcome measures

    The main outcomes included survival or mortality. Some studies evaluated neurological outcomes. The measures used are detailed in the following paragraphs.

    • Cerebral performance categories (CPC): this is a 5-category measure used to assess neurological outcome. Categories 1 (good cerebral performance: conscious, alert, capable of normal life) and 2 (moderate cerebral disability: conscious, alert, sufficient cerebral function for activities of daily life) are considered to show a good neurological outcome. Categories 3 (severe cerebral disability), 4 (coma/vegetative state) and 5 (certified brain death) are considered to be a poor neurological outcome.
