Torsion of extralobar pulmonary sequestration: a case report.
Article in Journal of surgical 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
Extralobar pulmonary sequestration (ELS) with torsion is rare in adolescents and mimics posterior mediastinal tumours, posing diagnostic challenges. An 11-year-old boy presented with acute chest pain. Contrast-enhanced computed tomography revealed a non-enhancing homogeneous mass with pleural effusion, while magnetic resonance imaging showed isointense T1 and hypointense T2 signals. Despite initial uncertainty regarding neoplasm, the acute presentation contrasted with the indolent course of posterior mediastinal tumours. History of abnormal prenatal ultrasonography facilitated diagnosis of torsed ELS. Video-assisted thoracoscopic surgery confirmed infarcted ELS with torsion, and the patient recovered uneventfully. This case highlights the importance of including ELS torsion in the differential diagnosis of posterior mediastinal masses and underscores the diagnostic value of prenatal imaging history.
