Echocardiography assessment of aortic elasticity as a vascular marker in hypertensive vs. healthy individuals.
Article in Scientific reports, 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
Hypertension contributes to arterial stiffness and may promote early atherosclerosis. Assessing aortic elasticity non-invasively could help identify early vascular changes before clinical atherosclerotic disease manifests. This study aimed to compare aortic elasticity parameters between hypertensive and healthy individuals using echocardiography to evaluate their association with hypertension and potential value in early vascular risk assessment. In this case-control study, 140 participants aged 30-60 were divided into two equal groups: newly diagnosed hypertensive patients and had no significant difference (P value > 0.05) in age- and sex with healthy controls. Transthoracic echocardiography was used to assess aortic elasticity indices, including aortic strain (relative change in diameter), distensibility (diameter change per pressure change), stiffness index (pressure-diameter relationship), and Peterson's elastic modulus (a measure of arterial wall resistance to deformation). Logistic regression and ROC analysis were performed to assess diagnostic value. Hypertensive patients showed significantly lower strain and distensibility and higher stiffness index and elastic modulus compared to controls (p < 0.001). These parameters demonstrated high diagnostic performance, with area under the curve (AUC) values of 0.97-0.99 for identifying hypertensive individuals, suggesting their potential utility in detecting early vascular stiffening. Echocardiographic measures of aortic elasticity differ significantly between hypertensive and healthy individuals. These indices may serve as useful, non-invasive markers for early vascular changes associated with hypertension. However, as this was an observational study, further longitudinal research is warranted to confirm their predictive value for atherosclerosis. The correlation between increased stiffness and inflammatory markers such as CRP suggests that further research is warranted to explore additional inflammatory indices.
