a Neurological functional scores 24 h after cardiac arrest (CA) in rats subjected to 6 min CA and 12 min CA. Mann-Whitney U test was used to test statistical difference. n = 5 for each group. b Brain electrical recovery after CA measured by electroencephalogram. Two-way ANOVA followed by Sidak’s corrections was used to test statistical difference. n = 3 for each group. c Serial modified Cox (mCOx) measurements early after successful resuscitation among groups. Two-way repeated measures ANOVA followed by Sidak’s corrections was used to test statistical difference. n = 12 for each group. Data are presented as mean ± SEM. *P < .05, **P < .01, ***P < .001, ****P < .0001
