Registered outcomes 12
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | First-pass intubation success rate | The time from enrollment to completion of intubation (usually within 10 minutes). | Proportion of participants with successful endotracheal tube placement on the first laryngoscopic attempt, confirmed by end-tidal carbon dioxide monitoring. | ClinicalTrials.gov |
| Secondary | Intubation time | The time from enrollment to completion of intubation (usually within 10 minutes). | Time in seconds from insertion of the laryngoscope into the oral cavity until the endotracheal tube passes through the glottis. | ClinicalTrials.gov |
| Secondary | Severe complications occurring within 2 minutes after intubation were defined as severe hypoxemia (peripheral SpO₂ <80%), severe hypotension (systolic blood pressure <65 mmHg), initiation of vasoactive agents, cardiac arrest, or death. | From enrollment to the 2 minutes after intubation | ClinicalTrials.gov | |
| Secondary | AI recall | The time from enrollment to completion of intubation (usually within 10 minutes). | True-positive anatomical detections divided by true-positive plus false-negative detections, assessed against reference annotations. | ClinicalTrials.gov |
| Secondary | Duration of mechanical ventilation | From enrollment to the end of treatment at 8 weeks | Duration of mechanical ventilation, measured in days. | ClinicalTrials.gov |
| Secondary | 28-day all-cause mortality | From enrollment through day 28. | Proportion of participants who die from any cause within 28 days after enrollment. | ClinicalTrials.gov |
| Secondary | ICU length of stay | From enrollment through the end of treatment, up to 8 weeks. | Duration of intensive care unit stay, measured in days. | ClinicalTrials.gov |
| Secondary | Total hospital length of stay | From enrollment through the end of treatment, up to 8 weeks. | Total duration of hospitalization, measured in days. | ClinicalTrials.gov |
| Secondary | AI precision | Video acquired from enrollment to completion of intubation, usually within 10 minutes. | True-positive anatomical detections divided by true-positive plus false-positive detections, assessed against reference annotations. | ClinicalTrials.gov |
| Secondary | AI specificity | Video acquired from enrollment to completion of intubation, usually within 10 minutes. | True-negative assessments divided by true-negative plus false-positive assessments, assessed against reference annotations. | ClinicalTrials.gov |
| Secondary | AI F1 score | Video acquired from enrollment to completion of intubation, usually within 10 minutes. | Harmonic mean of precision and recall: 2 x precision x recall / (precision + recall). | ClinicalTrials.gov |
| Secondary | Mean average precision (mAP) | Video acquired from enrollment to completion of intubation, usually within 10 minutes. | Mean of average precision across the evaluated anatomical classes against reference annotations. | ClinicalTrials.gov |
