Pneumomediastinum as a postinfectious complication of COVID-19 in paediatric patient.
Article in BMJ case reports, 2023. 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
An adolescent boy presented to the clinic with upper chest pain, anterior neck pain and difficulty swallowing 3 weeks following a COVID-19 infection. The pain started a few days before while participating in football practice. He reported no significant trauma or specific incidence when the pain began. His vital signs were stable and within normal limits. There was tenderness to palpation in the upper sternal area and low anterior neck. A chest X-ray was performed and was originally read by the primary care physician as unremarkable. This was followed by the official radiology read, which identified a spontaneous pneumomediastinum. A follow-up CT was confirmatory. The physician recommended rest and minimal activity, and the symptoms gradually resolved in 1 week. A follow-up 1 week after the initial visit revealed complete resolution by radiograph. One week later, a final set of radiographs confirmed sustained resolution of free air in the mediastinum. He was able to gradually return to normal activity.
