EMS arrival to first airway attempt was 2.7 minutes shorter in the LT group compared to the ETI group
ETI success rate of 51% in this trial lower than an expected 90% success rate as previously reported 
The LT group had a slightly higher number of OHCA patient with an initial shockable rhythm
A greater number of patients in the LT group received therapeutic hypothermia or cardiac catheterizaions at the receiving hospitals
Both treatments could have independently lead to increased likelihood of 72-hour survival
Trial does not assess quality of other factors that could influence 72-hour survival such as chest compression quality
Trial does not evaluate other methods of supraglottic airway
Result of the trial cannot be applied to an in-hospital setting
Both treatments could have independently lead to increased likelihood of 72-hour survival
