- Data presented as mean (95% confidence interval) (%). Time interval from collapse to return of spontaneous circulation (CPA-ROSC) cut-off value of 29 minutes in the hypothermia group and 15 minutes in the normothermia group had the highest combined sensitivity and specificity, with accuracies of 75.4% and 92.8%, respectively.
