Changes in Oxygen Saturation During Fiberoptic Bronchoscopy: High-Flow Nasal Cannula versus Standard Oxygen Therapy.
Observational study in Respiratory care, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundHypoxemia is a relatively common complication in stable patients during fiberoptic bronchoscopy (FOB). To prevent this complication, high-flow nasal cannula (HFNC) has been described as an alternative to standard oxygen therapy. However, the advantages of HFNC over standard oxygen therapy in acute care patients receiving supplemental oxygen before FOB performed with an oral approach are unknown.
methodsWe conducted an observational study that involved subjects with a presumptive diagnosis of pneumonia and a clinical indication for a bronchial aspirate sample. The type of oxygen support (standard oxygen therapy vs HFNC) was selected according to availability. The oxygen flow in the HFNC group was 60 L/min. In both groups, the F
resultsForty subjects were included, 20 in each group (HFNC and standard oxygen therapy). The study was performed on day 5 of hospitalization in the HFNC group and on day 4 in the standard oxygen therapy group (
conclusionsIn acute subjects who required oxygen support before FOB, the use of HFNC during FOB with an oral approach was associated with a smaller decrease in S
