A Rare Presentation of a Large Pleomorphic Rhabdomyosarcoma of the Inferior Vena Cava (IVC): A Case Report.
Article in Cureus, 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
Rhabdomyosarcoma (RMS) in adults is a rare, aggressive malignant tumour of mesenchymal origin with a poor prognosis. Hematoxylin and eosin (H&E) staining showing cellular population of large, rounded epithelioid, rhabdoid, plump spindled, and bizarre multinucleate tumour giant cells, as well as immunohistochemistry showing extensive staining of the atypical tumour cells for desmin and myogenic differentiation 1 gene (MyoD1) with multifocal coexpression of myogenin, are characteristic of RMS. We present a rare and unique case of a male in his 50s who presented with a two-week history of right-sided intermittent dull groin and back pain associated with bilateral lower limb swelling, who was diagnosed with a 9 cm right retroperitoneal pleomorphic RMS involving the inferior vena cava (IVC), causing complete IVC occlusion. He underwent an extensive en bloc resection of the tumour. We also discuss the signs, symptoms, relevant investigations, and various treatment options in managing a patient with pleomorphic RMS.
