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

BACKGROUND/

aimAngiomyomas are rare benign smooth muscle tumors originating from the tunica media of blood vessel walls, most frequently affecting the lower extremities in middle-aged women. CASE REPORT: We report the case of a 51-year-old female with a six-month history of a painful, palpable mass in the right heel. Physical examination revealed a soft, mobile, and tender subcutaneous nodule. Ultrasound imaging identified a 0.5 cm well-defined hypoechoic lesion in the subcutaneous layer, without internal blood flow, initially suspected to be an epidermoid cyst or fibrous tumor. Surgical excision of the lesion was performed, and histopathological analysis revealed a well-encapsulated tumor consisting of spindle-shaped cells with eosinophilic cytoplasm and bland nuclei, accompanied by vascular components. Immunohistochemical staining confirmed positive expression of SMA, establishing the diagnosis of angiomyoma. The patient experienced an uneventful postoperative recovery.

conclusionThis case highlights the diagnostic challenges of angiomyomas, given their nonspecific clinical presentation and imaging findings. While magnetic resonance imaging may reveal characteristic features such as strong gadolinium enhancement, definitive diagnosis relies on histopathological evaluation. Clinicians should include angiomyoma in the differential diagnosis of painful subcutaneous masses in the foot and ankle, particularly in middle-aged women. Surgical excision remains the definitive diagnostic and therapeutic approach, with low recurrence rates reported.
