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

A 75-year-old man presented with cognitive decline, headaches, and ataxic gait. Magnetic resonance imaging (MRI) revealed acute infarcts in multiple brain regions, and vessel wall MRI (VW-MRI) demonstrated concentric arterial wall thickening and enhancement in some intracranial arteries, initially suggesting primary central nervous system vasculitis (PCNSV). Despite immunosuppressive therapy, the patient developed further infarction. A skin biopsy revealed intravascular large B-cell lymphoma (IVLBCL), and autopsy revealed tumor cells in the arterial walls corresponding to the VW-MRI findings. This case highlights the risk of a misdiagnosis of PCNSV based solely on imaging findings and underscores the need for histological confirmation.
