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
Perivascular epithelioid cell tumors (PEComas) of the uterus are rare mesenchymal neoplasms characterized by myogenic and melanocytic differentiation. These tumors can mimic other uterine mesenchymal tumors in their clinical presentation and morphology. We report a case of a 58-year-old woman who presented with abnormal uterine bleeding. Initial imaging revealed an endometrial polyp, which was later diagnosed as a leiomyoma on excision biopsy. A subsequent hysterectomy with bilateral salpingectomy revealed a uterine neoplasm composed of spindled to epithelioid cells with low-grade cytologic atypia, infiltrative edges, and extensive lymphovascular invasions, initially suggestive of low-grade endometrial stromal sarcoma. However, immunohistochemical stains demonstrated tumor positivity for HMB45, desmin, and Cathepsin K, and genetic testing revealed a
