Cardiac arrest & resuscitation
Characteristics, outcomes, and prognostic factors in patients with hanging-induced out-of-hospital cardiac arrest: An analysis of a nationwide registry in Japan
Authors' conclusion
Prognosis following hanging-induced OHCAs was significantly worse compared to OHCAs of other causes.
