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

Primary leptomeningeal lymphoma (PLML) is a rare variant of primary central nervous system lymphoma, distinguished by the absence of parenchymal lesions. We describe an exceptionally rare case of PLML in an 86-year-old woman presenting with hydrocephalus. Magnetic resonance imaging showed ventricular enlargement over a two-week period, accompanied by faint periventricular contrast enhancement. To diagnose and treat her symptoms, an endoscopic ependymal biopsy and third ventriculostomy were performed concurrently, resulting in a pathological diagnosis of diffuse large B-cell lymphoma, specifically PLML, and symptom alleviation. The endoscopic approach proved effective and reasonable for the diagnosis and resolution of this atypical hydrocephalus.
