Blood pressure variability and white matter hyperintensities after ischemic stroke.
Article in Cerebral circulation - cognition and behavior, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Background: High blood pressure variability (BPV) may be a risk factor for stroke and dementia in patients with ischemic stroke, but the underlying mechanism is unknown. We aimed to investigate whether high BPV is associated with presence and progression of white matter hyperintensities (WMH). Methods: We performed a post-hoc analysis on the MRI substudy of the PRoFESS trial, including 771 patients with ischemic stroke who underwent MRI at baseline and after a median of 2.1 years. WMH were rated with a semi-quantitative scale. Visit-to-visit BPV was expressed as the coefficient of variation (interval 3-6 months, median number of visits 7). The association of BPV with WMH burden and progression was assessed with linear and logistic regression analyses adjusted for confounders. Results: BPV was associated with burden of periventricular WMH (β 0.36 95%CI 0.19-0.53, per one SD increase in BPV) and subcortical (log-transformed) WMH (β 0.25, 95%CI 0.08-0.42). BPV was not associated with periventricular (OR 1.09, 95%CI 0.94-1.27) and subcortical WMH progression (OR 1.15, 95%CI 0.99-1.35). Associations were independent of mean BP. Conclusion: High visit-to-visit BPV was associated with both subcortical and periventricular WMH burden in patients with ischemic stroke, but not with WMH progression in this study.
