1 · What the graph read from it

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.

2 · The registry

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

backgroundSupraglottic jet ventilation (SJV) is used during flexible bronchoscopy to improve oxygenation, but its impact on overall lung ventilation is unclear. Thoracic electrical impedance tomography (EIT) offers real-time monitoring of respiratory function.

methodsThis prospective pilot study enrolled patients undergoing flexible bronchoscopy. End-expiratory lung impedance (EELI) changes from baseline (ΔEELI) were measured at baseline (T0), oxygenation with Wei nasal jet (WNJ) (T1), SJV (T2), during bronchoscopy (T3), and post-bronchoscopy (T4). The primary outcome was ΔEELI at T2 vs. T3. Secondary outcomes included ΔEELI at other time points, ventilation distribution (ventral vs. total lung, ROIventral), hemodynamics, oxygen saturation (SpO

resultsAmong 27 patients, 5 experienced transient desaturation (no laryngeal mask ventilation needed). ΔEELI and SpO

conclusionsWhile SJV did not prevent the negative effects of bronchoscopy on lung ventilation and oxygenation, it maintained adequate SpO
