Pneumoparotid causing subcutaneous emphysema secondary to chronic habitual Valsalva behaviours in a 13-year-old girl.
Article in BJR case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Pneumoparotid is an unusual condition involving retrograde insufflation of air via the mouth into the parotid gland. In rare circumstances it can be complicated by subcutaneous emphysema. We describe a highly unusual case of rapid-onset facial swelling and limited eye-opening in an otherwise clinically well 13-year-old female. Computed tomography imaging showed pneumoparotid and extensive surgical emphysema involving the cervicofacial soft tissues and mediastinum. A detailed history revealed habitual Valsalva-related behaviours, including ear-popping and blowing bubbles in drinks. She was diagnosed with subcutaneous emphysema secondary to pneumoparotid, and her symptoms resolved with conservative management.
