Recurrent catamenial pneumothorax in an adolescent: A case report with review of diagnostic and therapeutic challenges.
Article in Respiratory medicine case reports, 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
Catamenial pneumothorax (CP) is a rare form of spontaneous pneumothorax associated with thoracic endometriosis and is exceptionally uncommon in adolescents. We report a 14-year-old girl with early menarche and heavy menses who presented with abdominal pain and was incidentally found to have a right-sided pneumothorax. Despite chest tube drainage, video-assisted thoracoscopic surgery (VATS) with bleb resection and pleurectomy, and subsequent chemical pleurodesis, she experienced recurrent episodes temporally associated with menstruation. A second VATS identified new blebs without diaphragmatic fenestrations or endometriotic lesions. Pathology was negative for lymphangioleiomyomatosis, while estrogen and progesterone receptor stains were also negative, leaving the case without histologic confirmation. Ultimately, the strong temporal association with menses and sustained remission after complete menstrual suppression with oral contraceptives supported a clinical diagnosis of catamenial pneumothorax.
