Vascular Leiomyosarcoma Masquerading as Chronic Deep Venous Thrombosis.
Article in Clinical nuclear medicine, 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
A 78-year-old man with a history of DVT on apixaban presented with bilateral leg pain and dyspnea. Chest CTA ruled out pulmonary embolism but revealed bilateral pulmonary nodules. Biopsy identified a spindle cell neoplasm. 18 F-FDG PET and duplex ultrasound imaging revealed intensely FDG-avid, intraluminal masses in the right femoral and popliteal veins. MRI confirmed lesions with peripheral enhancement. Biopsy of one of the femoral vein masses showed a high-grade spindle cell neoplasm positive for SMSA and desmin, consistent with leiomyosarcoma. This rare vascular tumor mimicked DVT, highlighting the importance of multimodal imaging and biopsy in diagnosing intravascular malignancies with metastatic potential.
