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
ObjectiveDermatofibrosarcoma protuberans is a low-to-intermediate-grade malignancy with high postoperative recurrence risk. It is often misdiagnosed as superficial venous malformation due to nonspecific manifestations and clinical features similar to those of other soft tissue tumors. Ultrasound examination is crucial for dermatofibrosarcoma protuberans evaluation; however, its value in differentiating dermatofibrosarcoma protuberans from superficial venous malformation remains underinvestigated.MethodsThis retrospective study analyzed and compared the clinical and ultrasonographic features between 41 histopathologically confirmed dermatofibrosarcoma protuberans cases and 41 superficial venous malformation cases. Clinical data included sex, age, tumor size, and location. Ultrasound findings were categorized into five types, and the following features were evaluated: shape, boundary, pattern, invasion depth, and vascularity.ResultsThe dermatofibrosarcoma protuberans tissues had significantly larger maximum diameters than superficial venous malformations (
