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

Autoimmune pancreatitis is a rare immunoglobulin G4-related disease characterized by a favorable response to steroids. However, its association with pancreatic cancer remains unclear. We report the case of a 71-year-old male who developed pancreatic cancer 1 month after completing a 7-year course of steroid therapy for autoimmune pancreatitis. Initially diagnosed based on elevated serum immunoglobulin G4 levels and characteristic imaging findings, the patient's autoimmune pancreatitis remained in remission during steroid therapy. Post-treatment imaging, positron emission tomography revealed a pancreatic tail mass leading to the differential diagnosis of autoimmune pancreatitis relapse versus pancreatic cancer. Histopathological examination confirmed adenocarcinoma, and the patient underwent successful neoadjuvant chemoradiotherapy and surgical resection. This case highlights the diagnostic challenges in distinguishing autoimmune pancreatitis from pancreatic cancer and emphasizes the importance of vigilant and long-term surveillance of patients with autoimmune pancreatitis, even in those with prolonged remission. Advanced imaging modalities and histopathological confirmation are essential for timely and accurate diagnosis.
