  1. aLinear effect for tertiles of time from restoration of spontaneous circulation (ROSC) to esophageal temperature of not more than 34°C (<120, 120 to 220, and >220 minutes). bHosmer-Lemeshow chi-squared = 2.67, P = 0.85, indicating good model fit. Temperature data between April 1995 and June 2008 were collected from 588 patients. cTotal amount of epinephrine in milligrams needed to achieve ROSC. dBladder temperature in degrees Celsius at beginning of cooling. eCardiac arrest with ventricular fibrillation or nonperfusing ventricular tachycardia as the initial cardiac rhythm on electrocardiogram.
