MRI features of Stewart-Treves syndrome: a case series and systematic review.
Synthesis in Japanese journal of radiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo comprehensively summarize the magnetic resonance imaging (MRI) features of angiosarcomas presenting as Stewart-Treves syndrome (STS) through a retrospective case series and systematic review of previous publications. MATERIALS AND
methodsWe identified five patients with STS from our institutional database and 25 patients with STS from 15 publications through a systemic review. We reviewed the MR features of 30 patients with STS, including five males and 25 females with a mean age of 59.5 years.
resultsThe tumors most commonly involved both the cutis and subcutis (17/25, 68.0%); the remaining tumors were limited to the cutis or subcutis. Multiple tumors were observed in more than half of the cases (16/27, 59.3%), and most of the tumors had poorly defined margins (26/28, 92.9%). The most common signal intensities of the tumors on T1-weighted images were intermediate (16/19, 84.2%), and the remainder were a mixture of intermediate and high, with a predominance of intermediate signal intensity. The signal intensities of the tumors on T2-weighted images were intermediate in seven cases (7/13, 53.8%), a mixture of intermediate and high in five cases (5/13, 38.5%), and a mixture of intermediate and low in one case (1/13, 7.7%). Available diffusion-weighted images from four institutional cases showed restricted diffusion of the tumors with mean apparent diffusion coefficient (ADC) values ranging from 0.77 × 10
conclusionTypical MRI features of angiosarcomas in STS were superficially located in multiple masses with ill-defined margins. Internal signal intensity was intermediate on T1-weighted images, and intermediate or a mixture of intermediate and high on T2-weighted images. ADC values obtained from the limited number of cases were low.
