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

We report a rare case of intraductal papillary mucinous carcinoma (IPMC) in a young male who initially presented with imaging findings suggestive of autoimmune pancreatitis (AIP) and was later diagnosed with tumor-associated pancreatitis. Despite symptom resolution with conservative treatment, follow-up imaging revealed a pancreatic tumor. Surgical resection confirmed the presence of IPMC with adenocarcinoma components. This case highlights the importance of excluding malignancy even in young patients with AIP-like features. Given the limited sensitivity of FDG-PET for early stage tumors, adjunctive modalities such as endoscopic ultrasound (EUS) and serial pancreatic juice aspiration cytological examination (SPACE) should be actively considered.
