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: Myoepithelial carcinoma is rare, and myoepithelial carcinoma occurring outside the head and neck is even rarer. We reported one case of retroperitoneal myoepithelial carcinoma. Case Summary: A 63-year-old woman who underwent computed tomography (CT) for progressive abdominal distension revealed a left retroperitoneal mass and subsequently underwent surgical treatment where the mass was completely removed with a postoperative diagnosis of retroperitoneal myoepithelial carcinoma. A follow-up CT review 40 days after surgery revealed a recurrence of the mass. After 8 months of chemotherapy and targeted immunotherapy, a follow-up review of the CT images revealed a gradual reduction in the mass. Four months after the cessation of chemotherapy and targeted drug combined immunotherapy, a follow-up review via CT revealed another recurrence and enlargement of the mass. Conclusion: CT of retroperitoneal myoepithelial carcinoma revealed a massive cystic solid mass in the abdominal cavity and retroperitoneum. The solid region of the mass was significantly enhanced and the cystic region was without enhancement on enhanced CT; the mass involved the adjacent duodenum, partial jejunum, and left renal vein. PET‒CT imaging revealed hypermetabolism in the solid region of the mass and no hypermetabolism in the cystic region.
