Double-lumen endotracheal tubes and bronchial blockers exhibit similar lung collapse physiology during lung isolation.
Trial report in Canadian journal of anaesthesia = Journal canadien d'anesthesie, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02919267 (Physiology of Lung Collapse Under One-Lung Ventilation), which is not on this map. Cited by 10 papers.
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.

Abstract
purposeDouble-lumen endotracheal tubes (DL-ETT) and bronchial blockers (BB) are frequently used to allow one-lung ventilation (OLV) during video-assisted thoracic surgery (VATS). Recently, faster lung collapse has been documented with a BB than with a DL-ETT. The physiologic mechanisms behind this faster collapse remained unknown. We aimed to measure ambient air absorption (V
methodsPatients undergoing VATS and OLV for lung resection were randomly assigned to have measurements made of V
resultsThirty-nine patients were included in the analyses. The mean (standard error of the mean [SEM]) V
conclusionsDuring OLV before pleural opening, entrainment of ambient air into the non-ventilated lung occurs when the lumen of the lung isolation device is kept open. This phenomenon is prevented by occluding the lumen of the isolation device before pleural opening, resulting in a progressive build-up of negative pressure in the non-ventilated lung. Future clinical studies are needed to confirm these physiologic results and their impact on lung collapse and operative outcomes.
