A comparative study of conventional, High-flow, and jet ventilation via the Wei nasal jet tube for oxygen therapy in patients undergoing bronchoscopic intervention under deep sedation: a randomized controlled trial.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Hypoxemia is a frequent complication in the bronchoscopic interventions (BI) under deep sedation due to shared airway challenges. The Wei nasal jet tube (WNJ) enables supraglottic jet oxygenation and ventilation (SJOV) without tracheal intubation, but its efficacy and safety compared to conventional oxygen therapy (COT) or high-flow nasal cannula (HFNC) in patients with mild-to-moderate airway stenosis remain unclear. Methods: In the prospective randomized controlled trial, 150 patients through BI under deep sedation were allocated to three groups: COT (fractional inspired oxygen (FiO Results: A sum of 150 patients participated in the study. The incidences of hypoxemia, severe hypoxemia, and MPPO were compared among the three groups. The overall incidence of hypoxemia differed significantly ( Conclusion: SJOV delivered via the Wei nasal jet tube improved intraoperative oxygenation and reduced hypoxemia compared with COT during bronchoscopic intervention under deep sedation, without increasing adverse events. These findings support SJOV as a feasible oxygenation and ventilation strategy for selected patients with mild-to-moderate airway stenosis.
