Leiomyosarcoma of the Breast: Case Report and Review of the Literature.
Article in European journal of breast health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Primary breast leiomyosarcoma is an extremely rare malignancy, accounting for approximately 1% of breast tumors and less than 5% of soft tissue sarcomas. Due to its rarity, standardized treatment guidelines remain unclear. We report the case of a 38-year-old woman who presented with a 3 cm, freely mobile breast nodule, initially classified as American College of Radiology Breast Imaging Reporting and Data System 4 on imaging. Core needle biopsy confirmed primary breast leiomyosarcoma, with histopathological and immunohistochemical analysis revealing strong positivity for α-smooth muscle actin, desmin, and H-caldesmon, consistent with smooth muscle differentiation. Epithelial, neural, and vascular markers were negative, ruling out differential diagnoses. The Ki-67 index was 15%, indicating moderate proliferative activity. Staging classified the tumor as T2N0M0 (Stage IIA, the American Joint Committee on Cancer 8
