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

Cerebral amyloid angiopathy (CAA) is a common yet underdiagnosed disease of the small brain vessels, resulting in acute vascular events as well as subcortical neurodegeneration. Currently, it is identified only at advanced stages due to the limitations of non-invasive diagnostic tools. Our pilot study evaluates metabolic and immune alterations in stroke patients with imaging-confirmed CAA. This prospective cohort study included stroke patients admitted to the University Hospital Erlangen with CAA diagnosis based on MRI findings. Metabolomic analysis of cerebrospinal fluid and serum samples was performed using liquid chromatography/mass spectrometry, focusing on caffeine metabolism and amino acid pathways. Immunophenotyping of leukocytes was conducted via flow cytometry. The study included 22 stroke patients, of whom 10 had an MRI-based diagnosis of CAA. Metabolomic analysis revealed consistently lower levels of caffeine-related metabolites in CAA patients with significant differences in 5-acetylamino-6-amino-3-methyluracil, paraxanthine, theobromine, 3,7-dimethyluric acid, 3-methylxanthine and 1-methylxanthine. Amino acid levels showed no significant differences. Immunophenotyping revealed a reduction in CD4
