Alzheimer's Disease Concurrent With Patent Foramen Ovale-Related Lacunar Infarcts and Extensive White Matter Hyperintensities: A Case Highlighting Biomarker-Clinical Staging Discordance.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
An elderly man with progressive memory decline met the 2024 National Institute on Aging and the Alzheimer's Association (NIA-AA) biological criteria for Alzheimer's disease (AD) - classified as stage C biologically but mild dementia clinically - revealing a clear staging mismatch. Recognizing this discordance led us to investigate additional comorbidities. He was found to have extensive white matter hyperintensities (WMHs) (Fazekas grade 3) and experienced multiple recurrent lacunar infarcts. Subsequent evaluation identified a patent foramen ovale (PFO) causing right-to-left shunting and paradoxical embolism. This case underscores the necessity of detecting biological-clinical discordance in AD, actively screening for cerebrovascular comorbidities such as WMHs and infarcts, and accurately identifying underlying causes to optimize patient management and enrich AD clinical research.
