Study Procedures
Participants were randomized by teams of 2 using an online randomizer tool into either the control group or intervention group. Airway practitioners were paired with airway assistants in a nonrandom fashion. Randomization occurred at the level of the team, was stratified by study site, and conducted in blocks of 4 to ensure equal distribution of teams across study groups. Study packages were prepared with opaque envelopes and administered by site research coordinators to achieve allocation concealment. See
