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

Tumor-associated blood eosinophilia (TABE) and tumor-associated tissue eosinophilia (TATE) are rare in solid cancers, and reports of eosinophilic peritonitis in these cases are extremely limited. We present the case of a 68-year-old man with pancreatic and lung cancer who developed severe eosinophilia and eosinophilic peritonitis. Despite corticosteroid therapy, refractory ascites led to a decline in performance status. An autopsy confirmed undifferentiated pancreatic adenocarcinoma with TABE, TATE, and lung cancer. This case underscores the diagnostic challenges of multiple primary malignancies with eosinophilia and highlights the need for individualized management strategies for tumor-associated eosinophilic disorders.
