Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Video Laryngoscope Group | For patients assigned to the video laryngoscope group, the operator will use a video laryngoscope on the first laryngoscopy attempt. A video laryngoscope will be defined as a laryngoscope with a camera and a video screen. Trial protocol will not dictate the brand of video laryngoscope.~Video Laryngoscope: Laryngoscope with a camera and a video screen | 600 | 705 | OG000 |
| Group 2 | Direct Laryngoscope Group | For patients assigned to the direct laryngoscope group, the operator will use a direct laryngoscope on the first laryngoscopy attempt. A direct laryngoscope will be defined as a laryngoscope without a camera or a video screen. Trial protocol will not dictate the brand of direct laryngoscope or the blade shape.~Direct Laryngoscope: Laryngoscope without a camera or a video screen | 504 | 712 | OG001 |
