Renal venous hemangioma: Report of a rare case.
Article in Experimental and therapeutic medicine, 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
Renal hemangiomas are typically asymptomatic and considered benign lesions. Arterial hemangiomas are common; however, venous hemangiomas are extremely rare and frequently found incidentally during imaging examinations, which can result in misdiagnosis. The present study reported the case of a 37-year-old man with renal vein hemangioma, initially diagnosed as a left retroperitoneal space-occupying lesion on computed tomography (CT). The patient complained of frequent urination for 1 week, urgency for 1 week and hematuria for 1 day. Renal CT revealed a 3-cm space-occupying lesion in the left retroperitoneum. Subsequently, surgical resection was performed and the venous hemangioma was identified as a left renal vein aneurysm. Due to the rarity of venous hemangioma and the lack of standardized imaging criteria, it is frequently misdiagnosed, making its preoperative diagnosis challenging. The present study summarized and reported this rare case to serve as a reference for clinical physicians.
