Association Between Short-Term Blood Pressure Variability and the Alzheimer's Disease Continuum.
Article in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
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
backgroundEmerging evidence indicates that blood pressure variability (BPV) is a modifiable vascular risk factor for Alzheimer's disease (AD). Herein, we aimed to systematically evaluate the potential role of short-term BPV across the AD continuum.
methodsThis study included 263 patients on the AD continuum from the Chinese Imaging, Biomarkers, and Lifestyle study between January 1, 2023, and December 31, 2023. 24-h ambulatory blood pressure monitoring was performed to obtain blood pressure measurements and evaluate BPV. Partial Spearman's correlation and restricted cubic spline analysis were performed to assess the associations between BPV and neuropsychological tests, cerebrospinal fluid biomarkers, and multimodal neuroimaging measures, respectively. The mediating effects of multimodal neuroimaging measures on the association between BPV and neuropsychiatric symptoms (NPS) were analyzed.
resultsThe elevated standard deviation (SD) and average real variability of nightly diastolic blood pressure (DBP) were correlated with higher Neuropsychiatric Inventory (NPI) scores (r = 0.19, p = 0.034; r = 0.22, p = 0.013). The increased SD of nightly systolic blood pressure (SBP) was correlated with increased Hamilton Anxiety Scale (HAMA) scores and total tau levels (r = 0.20, p = 0.026; r = 0.17, p = 0.027), and elevated coefficient of variation (CV) of nightly SBP was correlated with higher HAMA scores and lower Aβ
conclusionThis study suggests that short-term BPV may play a role in the AD continuum. These findings provide evidence of a vascular pathway to AD, as well as a potential and accessible intervention target for patients on the AD continuum.
