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

Herein, we report a rare case of pancreatic metastasis originating from a malignant phyllodes tumor of the breast. A 45-year-old woman initially underwent a partial mastectomy for malignant phyllodes tumor of the left breast, followed by a total mastectomy for local recurrence. Six years later, the patient presented with abdominal pain. Computed tomography revealed a heterogeneous mass with cystic degeneration in the pancreatic tail, morphologically resembling the previously resected breast lesions. Based on the patient's history and imaging findings, pancreatic metastasis from malignant phyllodes tumor was suspected. Endoscopic ultrasound-guided fine-needle aspiration of the solid component was performed, and histopathological examination revealed a sheet-like proliferation of atypical cells with spindle-shaped enlarged nuclei within an eosinophilic stroma. Immunohistochemical staining for AE1/3 cytokeratin was negative, consistent with metastatic malignant phyllodes tumor. The patient declined further treatment and died approximately two months after diagnosis.
