How High-Flow Nasal Cannula Is Impacted by Nasogastric/Esophageal Tube: A Bench Study.
Article in Critical care explorations, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
High-flow nasal cannula (HFNC) is a common noninvasive respiratory therapy for respiratory failure, offering positive airway pressure and dead space clearance. In critically ill patients, additional nasal tubes for feeding or monitoring are often required, but their effect on HFNC performance is not well understood. This bench study evaluated the impact of nasal tube placement on dead space clearance, nasopharyngeal pressure, and airway resistance using standard and asymmetrical cannulas. Inserting a 5-Fr tube with a standard cannula had very little effect, whereas bigger sizes (12-Fr and 16-Fr) slightly increased airway pressure and reduce Co2 clearance. An asymmetrical cannula exhibited variable effects depending on the side of the tube placement. Higher pressure and better clearance were achieved with a tube placed in the smaller cannula side. However, if occlusion of the two nares becomes excessive with the tube in place, downsizing the cannula might be recommended.
