Treatment Sequencing in Renal Ewing's Sarcoma With Inferior Vena Cava (IVC) Thrombus: A Comparative Case-Based Analysis.
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
Renal Ewing's sarcoma with inferior vena cava (IVC) tumour thrombus is a rare and aggressive malignancy that may mimic renal cell carcinoma (RCC) on imaging, creating diagnostic and therapeutic challenges. We report two young female patients presenting with large renal masses and level II IVC tumour thrombus who were managed using contrasting treatment sequences. In the first patient, image-guided biopsy established the diagnosis, allowing neoadjuvant systemic chemotherapy that resulted in substantial tumour and thrombus downsizing and facilitated subsequent surgical resection. In the second patient, persistent haematuria and progressive anaemia prompted urgent upfront surgery, which was followed by significant postoperative morbidity and delayed initiation of systemic chemotherapy. These contrasting cases highlight the potential value of early tissue diagnosis in selected clinically stable patients with atypical renal masses and emphasise that treatment sequencing should be individualised according to clinical status, tumour extent, thrombus burden, and multidisciplinary assessment.
