Registered outcomes 2
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Percentage of Participants With at Least One Episode of Subclinical Hypoxaemia (90% ≤ SpO₂ < 95% for ≥10 Seconds)During sedated gastrointestinal endoscopy | Periprocedural | Subclinical hypoxemia was defined as pulse oximetry-derived SpO₂ decreasing to 90% ≤ SpO₂ \< 95% and sustained for at least 10 seconds at any point during sedated gastrointestinal endoscopy . SpO₂ was monitored continuously throughout the procedure. The outcome was the proportion of participants who experienced at least one qualifying episode; each participant was counted only once regardless of the number of episodes. Results were reported as the number and percentage of participants (n/N, %) in each group. | ClinicalTrials.gov |
