Carcinomatous Meningitis and Hydrocephalus in Plasmacytoid Urothelial Carcinoma of the Urinary Bladder With Extremely Elevated CA19-9 Levels.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
This case report describes a rare and aggressive presentation of plasmacytoid urothelial carcinoma (PUC) with carcinomatous meningitis, hydrocephalus, extensive organ involvement, and extremely elevated serum CA19-9 levels. Autopsy findings revealed that PUC of the urinary bladder origin caused carcinomatous meningitis and hydrocephalus, with exacerbation of hydrocephalus as the direct cause of death. Immunohistochemical studies confirmed the bladder origin of PUC, and PUC cells were positive for CA19-9, a tumor marker commonly associated with gastrointestinal malignancies, suggesting that the markedly high serum CA19-9 level was related to the tumor-producing mechanism.
