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

Malignant phyllodes tumor is a rare and aggressive breast neoplasm with the potential for rapid and recurrent growth. We present the case of a 56-year-old woman from San Martín, Peru, with a left breast mass exhibiting exponential growth, ulceration, necrosis, and asymmetry. Physical examination revealed a multinodular, purplish-red, indurated, and slightly painful mass. Ultrasound showed a 12-cm hypoechoic, heterogeneous mass with areas of necrosis, increased vascularity, and contact with the muscle layer (Breast Imaging Reporting and Data System category 4). Core biopsy revealed a fibroepithelial neoplasm with high mitotic activity (10/10 HPF). The patient underwent left total mastectomy with subsequent margin extension and partial-thickness skin grafting, achieving complete resection and satisfactory recovery. This case highlights the challenges in the diagnosis and surgical management of this pathology in resource-limited settings where timely surgery plays a crucial role in treatment and prevents recurrence.
