Patient / Population Intervention / Exposure Comparison Outcome
In 9,296 adults with out-of-hospital cardiac arrest, an i-gel supraglottic airway did not change favourable neurologic outcome at discharge versus endotracheal intubation.

Discussion & critique
SGA is a reasonable primary strategy in OHCA when ETI experience is limited; outcomes equivalent.
