1 · What the graph read from it

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.

2 · The registry

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

introductionDesmoid-type fibromatosis of the breast is a rare, locally aggressive fibroblastic tumor that lacks metastatic potential but demonstrates infiltrative growth and a tendency for local recurrence. Because its imaging characteristics often resemble those of breast carcinoma, establishing a preoperative diagnosis can be challenging. CASE PRESENTATION: A 57-year-old woman was referred after screening mammography detected a spiculated, high-density mass in the right breast. Ultrasonography demonstrated an irregular hypoechoic mass measuring approximately 36 mm in the upper inner portion of the breast with peripheral vascularity, findings suspicious for malignancy. Core needle biopsy revealed proliferation of spindle-shaped cells with minimal atypia and nuclear β-catenin positivity, suggesting desmoid-type fibromatosis. Tumor excision was subsequently performed for definitive diagnosis and local control. Histopathological examination confirmed desmoid-type fibromatosis with infiltrative growth into the surrounding adipose tissue. Focal margin involvement was identified, and the patient has been managed with careful follow-up.

conclusionsBreast desmoid-type fibromatosis is a rare tumor that can closely mimic breast carcinoma on imaging studies. Histopathological evaluation is essential for establishing the diagnosis. Because positive surgical margins have been associated with an increased risk of local recurrence, careful postoperative follow-up is warranted.
