S100B and cardiac arrest: We determined that serum levels of S100B (odds ratio 1.099, 95% CI 1.042–1.175), VCAM (odds ratio 15.202, 95% CI 2.805–120.427), PAI-1 (odds ratio 2.537, 95% CI 1.229–6.152), and IL-1β (odds ratio 1.299, 95% CI 1.043–1.657) were positively correlated with mortality within 24 hours after cardiac arrest (Table 4).
