Features of pediatric spontaneous pneumomediastinum: a single-center, retrospective case series.
Article in Frontiers in pediatrics, 2026. 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
Introduction: The clinical and epidemiological features of spontaneous pneumomediastinum (SPM) have not been fully characterized, and no previous studies have investigated the association between the onset of SPM and meteorological factors. This study aimed to examine the features of pediatric SPM and to investigate the association between its onset and meteorological factors. Methods: The medical records of patients aged 1-18 years diagnosed with SPM between January 2012 and December 2023 were retrospectively reviewed. Meteorological data for the same 12-year period were extracted from the Japan Meteorological Agency website. Multivariable logistic regression analysis was performed to evaluate the association between the onset of SPM and monthly meteorological factors. Results: Overall, 39 SPM cases were identified, including 1 recurrence. Of these, 34 (87.2%) were male with a median age at onset of 15.0 years. The median body mass index of the 26 boys with available data was 19.0 kg/m Conclusions: Patients diagnosed with SPM at the authors' hospital were predominantly adolescent boys with slim builds. We suggest that SPM should be considered as a differential diagnosis in cases of chest pain in slender adolescent boys. No clear association between the onset of SPM and meteorological parameters was identified; further studies using more robust methods are necessary.
