Catamenial Pneumothorax Without Thoracic Endometriosis: A Case Report From the Gulf Cooperation Council (GCC) Region.

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 is a rare clinical condition first described over seven decades ago. It typically occurs within 72 hours before or after menstruation and is most frequently observed in women of reproductive age. Reports from the Gulf Cooperation Council (GCC) region, including Qatar, remain limited, and underreporting has also been noted in developed countries such as Australia. This report presents a case of catamenial pneumothorax without evidence of thoracic abnormal endometriosis. A 37-year-old woman presented repeatedly to the emergency department with chest pain occurring during menstruation. Chest radiography showed a right-sided pneumothorax. Video-assisted thoracoscopy revealed right upper lobe blebs, which were excised. Laparoscopy identified the spread of endometrial tissue in the pelvis, ovaries, and uterus. The patient was treated with hormonal oral contraceptive therapy and remains under outpatient follow-up. Catamenial pneumothorax can occur in the absence of endometrial thoracic tissue. A high index of suspicion is essential for diagnosis in reproductive-aged women with recurrent spontaneous pneumothorax.
