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 neuroendocrine tumors (PanNETs) are rare epithelial neoplasms with endocrine differentiation. Although most PanNETs exhibit typical cytological features, uncommon morphological variants occasionally occur. We report the first case of a rhabdoid-type PanNET diagnosed solely by cytology. A 48-year-old woman was incidentally found to have a pancreatic head mass. Endoscopic ultrasound-guided fine-needle aspiration cytology revealed tumor cells with eccentric nuclei, granular chromatin, and prominent eosinophilic intracytoplasmic inclusions, which were highlighted by Giemsa staining. Immunocytochemistry demonstrated strong cytokeratin positivity within the inclusions along with the expression of neuroendocrine markers. This case underscores that rhabdoid-type PanNET can be diagnosed through the cytological identification of distinctive intracytoplasmic inclusions and confirmed by immunocytochemistry. Awareness of this rare phenotype is essential for accurate diagnosis and improved clinicopathological understanding of PanNET variants.
