Relationship between subendocardial viability ratio and cardiovascular disease risk in hypertensive patients.

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: The subendocardial viability ratio (SEVR), which correlates with coronary flow reserve, has been proposed as an indirect prognostic marker for cardiovascular disease (CVD). This study aimed to investigate the relationship between SEVR and cardiovascular risk scores, and to evaluate its value in identifying increased cardiovascular risk in hypertensive population. Methods: A total of 1,380 participants (782 hypertensive patients and 598 normotensive controls) were enrolled. Demographic characteristics, laboratory parameters, arterial stiffness, left ventricular structural and functional indices, and 10-year atherosclerotic CVD (ASCVD) risk calculated via the China Atherosclerotic CVD Risk Prediction model (China-PAR) were collected and analyzed. Multivariable linear regression and logistic regression analyses were conducted to identify independent determinants of SEVR and factors linked to high ASCVD risk (>10%). Results: Mean SEVR was significantly lower in the hypertensive group than in the control group (130.75% Conclusions: SEVR is inversely associated with 10Y-ASCVD risk in individuals with hypertension and remains an independent indicator after adjustment for conventional risk factors. As a noninvasive and cost-effective marker reflecting myocardial oxygen supply-demand balance, SEVR has the potential to add complementary value to current cardiovascular risk assessment models, thereby refining risk stratification in patients with hypertension.
