  1. Temperature data between April 1995 and June 2008 were collected from 588 patients. Data are presented as number (percentage). Fisher exact test, Pearson chi-square test, and Wald test for comparing the cooling methods with 'endovascular' as reference were used to compare variables, such as favorable and unfavorable neurologic outcome (cerebral performance category [CPC] 1-2 versus 3-4) groups, in the survivors and dead. IV, intravenous.
