The influence of extreme cold ambient temperature on out of hospital cardiac arrest: A systemic review and meta-analysis

Abstract

Many researches have demonstrated the effects of the extreme cold ambient temperature on the risk of out-of-hospital cardiac arrest (OHCA); yet, the results have been inconsistent. We performed a meta-analysis to evaluate whether extreme cold ambient temperature is related to OHCA.
