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

introductionCerebral amyloid angiopathy (CAA) is characterized by impaired vascular amyloid-β clearance, distinct from Alzheimer's disease (AD), underscoring the need to clarify its molecular basis for predicting therapy-related amyloid-related imaging abnormalities.

methodsWe analyzed post-mortem brain proteomics from Religious Orders Study and Rush Memory and Aging Project (ROS/MAP) and cerebrospinal fluid (CSF) proteomics from Alzheimer's Disease Neuroimaging Initiative (ADNI) to identify CAA-associated proteins and network modules, delineate their biological processes and cellular origins, and determine their diagnostic performance.

resultsProteomics analysis identified 30 proteins as associated with CAA severity, enriched in pathways distinct from AD pathology, with 11 replicated in ADNI. Two CAA-associated modules were enriched for microglial vesicle transport and astrocytic potassium-ion homeostasis. Pseudotime analysis demonstrated a molecular trajectory aligned with increasing CAA severity. Three proteins (RCSD1, FRZB, AKAP6) improved CAA classification beyond demographics and APOE ε4. DISCUSSION: This integrative proteomics analysis identifies distinct, reproducible molecular signatures of CAA, revealing glia-mediated pathways and promising biomarkers for CAA detection and therapy-related risk assessment.
