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

Recurrence of intraductal papillary mucinous neoplasms (IPMNs) in the remnant pancreas after surgery is a significant clinical challenge. A 68-year-old woman was incidentally found to have a 50-mm mixed-type intraductal papillary mucinous carcinoma (IPMC) in the pancreatic head during a health check. She underwent subtotal stomach-preserving pancreaticoduodenectomy with pancreatogastrostomy. Pathology revealed intestinal-type IPMC (pStage IA) with venous invasion and negative margins. Adjuvant oral S-1 chemotherapy was administered for six months. Eighteen months later, she developed rapid increases in HbA1c and tumor markers. Computed tomography showed 8-mm main pancreatic duct dilation in the remnant pancreas. Upper gastrointestinal endoscopy revealed a papillary tumor extending into the gastric mucosa, and biopsy confirmed adenocarcinoma. She was diagnosed with recurrent IPMC in the remnant pancreas and underwent total pancreatectomy with splenectomy. Intraoperative gastric endoscopy determined the extent of gastric wall resection. Postoperative chylous leakage occurred but resolved, and she was discharged on day 26. Pathology revealed non-invasive gastric-type IPMC, distinct from the intestinal-type lesion in the initial surgery. This case represents a rare metachronous recurrence of gastric-type IPMC following resection of intestinal-type IPMC, emphasizing the need for vigilant long-term surveillance and awareness of potential histologic subtype changes.
