Airway Compromise due to Retropharyngeal Emphysema-A Rare Complication of an Extravasated Peripherally Inserted Central Venous Catheter.
Article in Case reports in anesthesiology, 2019. 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
A 48-year-old woman was scheduled for flexible bronchoscopy, video-assisted thoracoscopic surgery and mediastinal washout. She had developed voice changes, difficulty swallowing, shortness of breath with a fever and increased respiratory rate in intensive care unit 12 days after a double liver and kidney transplantation. Computerised tomography of neck and chest demonstrated extensive retropharyngeal and subcutaneous emphysema, laryngeal distortion and pneumo-mediastinum; however, the causative factors were not immediately obvious. Intraoperatively, an un-anticipated diagnosis of extravasated peripherally inserted central venous cannula (PICC) was made. Total parenteral nutrition had extravasated into the mediastinum and thorax. Subsequent inflammation and infection resulted in air pocket formation. The retropharyngeal air pockets were caused by mediastinal emphysema tracking through the tissue planes to the anterior and posterior larynx. Awareness of the tip position and accompanying clinical and radiological enquiry, must be performed prior to use of PICC lines in critically ill patients.
