Hyperacute Superior Vena Cava Syndrome Secondary to Central Venous Catheter-Associated Thrombosis in a Patient with Tongue Cancer: An Unusually Rapid Presentation.
Article in Cureus, 2025. 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
Superior vena cava (SVC) syndrome is most often caused by malignant compression or thrombus formation and typically presents with progressive symptoms over weeks to months, while even acute cases usually evolve over several hours to days. We report a rare case of hyperacute SVC obstruction in a 53-year-old man with recurrent tongue carcinoma, a Hickman line in situ, and therapeutic anticoagulation for a recent pulmonary embolism. He developed profound cyanosis, facial and upper body swelling, and transient loss of consciousness within less than an hour. Imaging revealed a central line-associated thrombus causing complete SVC occlusion, and multidisciplinary input was required to balance the risks of catheter removal versus retention. This case underscores the importance of rapid recognition and coordinated management of SVC syndrome in high-risk oncology patients with central venous access.
