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

Pancreatic ductal adenocarcinoma (PDAC) rarely metastasizes to the gastrointestinal tract. Herein, we report a case of gastric metastasis from PDAC. An 83-year-old woman presented with a mass in the pancreatic tail. CT revealed a 5 cm neoplastic lesion in the pancreatic tail invading the splenic vessels and parenchyma, with lymph node metastasis. Collateral veins developed in the posterior stomach wall nine courses of chemotherapy were administered. After chemotherapy, esophagogastroduodenoscopy revealed an irregularly elevated lesion in the gastric body, which was identified as an adenocarcinoma. These lesions were considered resectable, and surgery, including distal pancreatectomy, splenectomy, lymph node dissection, and partial gastrectomy, was performed. Pathological examination revealed that the stomach wall had an extension of well-differentiated adenocarcinoma, mainly in the submucosa. The immunohistochemical staining pattern was similar to PDAC; therefore, gastric metastasis was diagnosed. The final pathological diagnosis was pT3N1M1 (stomach, LYM), pStage IV.
