Functional Markers of Vascular Aging: Subendocardial Viability Ratio, Augmentation Pressure, and Augmentation Index as Links to Atherosclerotic Cardiovascular Disease Risk.
Article in Journal of clinical hypertension (Greenwich, Conn.), 2026. 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
This study investigated the correlation of functional hemodynamic parameters, including subendocardial viability ratio (SEVR), augmentation pressure (AP) and heart-rate-corrected augmentation index (Aix@75), with age and atherosclerotic cardiovascular disease (ASCVD) risk in a Chinese population. A total of 3,354 participants aged 18-80 years with left ventricular ejection fraction >55% were enrolled in this cross-sectional study. Functional hemodynamic parameters were assessed by pulse wave analysis, and the 10-year ASCVD risk (10Y-ASCVDR) was estimated using the China-PAR model. Multivariable logistic regression was used to identify independent correlates of elevated estimated 10Y-ASCVDR. Results showed that 10Y-ASCVDR was inversely correlated with SEVR (r = -0.171, p < 0.001) and positively correlated with AP (r = 0.452, p < 0.001) and Aix@75 (r = 0.236, p < 0.001). Stepwise multivariable linear regression identified SEVR, AP and Aix@75 as independent correlates of estimated 10-year ASCVD risk (p < 0.001). In conclusion, SEVR, AP and Aix@75 are independent correlates of estimated 10-year ASCVD risk, and together provide a functional hemodynamic profile that independently correlates with estimated risk beyond traditional factors, suggesting their potential role as supplementary tools for cardiovascular risk stratification. These findings offer a valuable supplemental approach for improving cardiovascular risk assessment in clinical practice.
