Results of all three trials are consistent with respect to the primary outcome, with point estimates supporting an advantage from hypothermia: the relative risk associated with cooling was 0.82 in the CoolCap research, 0.72 in the NICHD trial , and 0.86 in the present trial. Our categorization of neurologic outcomes is in keeping with which used in the CoolCap and NICHD trials and earlier systematic reviews,12-17 facilitating the assessment of our findings with previous results. We found a substantial increase in the rate of survival without neurologic abnormality with cooling ; the NICHD and CoolCap trials, which were smaller than the present trial, demonstrated nonsignificant benefits with respect to the outcome but had comparable point estimates.
