In the post-VF arrest patients, there was a good outcome (discharge to home or to rehabilitation) in both groups of 50%. In the post-non-VF arrest patients, there was a good outcome at hospital discharge of 12% in the paramedic cooled group compared with 9% in the standard care group. The study was stopped at the interim analysis due to a lack of difference in the primary outcome measure (outcome at hospital discharge) between the two groups (futility).
