Modulatory Effects of Hypertension on Aging-Related White Matter Hyperintensities: A Comparative Study Among Stroke Patients and Stroke-Free Community-Based Cohort.

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
The increased vulnerability of the aging human brain to hypertension-induced neurovascular impairments, including cerebral small vessel diseases (SVD), marked by MRI-visible white matter hyperintensities (WMH), is well recognized. We examined WMH burdens between stroke patients and stroke-free participants across three age groups and explored patterns of modifiable risk factors, specifically the modulating effects of hypertension on WMH burden, providing insights for potential therapeutic interventions. This study comprised one hospital-based cohort of 254 stroke patients and another community-based cohort of 254 stroke-free normative participants. Clinical variables were obtained consecutively, and MRI neuroimaging classified WMH as absent, mild, moderate, or severe. A step-by-step statistical analysis was performed to explore the said gaps. There were 508 participants (mean age 63.5 ± 8.9 years) with 285 males. A similar prevalence but different WMH burden was recorded between stroke and normative cohorts across different age groups. The modulating effect of hypertension on WMH severity varied across age groups and is greater in middle-aged adults; intriguingly, this effect diminished in elderly adults (b = -0.882, 95%CI [-1.591, -0.172], t = -2.442, p = 0.015). It was shown that, in a non-uniform fashion across different age groups, hypertension is a culprit risk factor for exacerbating WMH severity, and middle-aged adults are the most vulnerable. While the elevation of systolic blood pressure predisposes adults to brain white matter deterioration, the decline in diastolic blood pressure suggests a protective role. Recognizing hypertension as a modifiable risk factor and understanding the aging-related changes in blood pressure patterns open avenues for developing age-specific strategies for the mitigation and management of WMH progression.
