Alterations in Cardiac Structure and Function Associated With Sub-Severe Aortic Stenosis Progression: The ARIC Study.
Article in Journal of the American Heart Association, 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
backgroundAmerican Heart Association and American College of Cardiology guidelines articulate 4 aortic stenosis (AS) stages to highlight its progressive nature, but limited data exist on cardiac alterations in sub-severe stages.
methodsARIC (Atherosclerosis Risk in Communities) study participants with protocol echocardiography at Visit 5 (V5; 2011-2013) and free of aortic valve (AV) replacement or cardiovascular disease were classified by ACC/AHA AS stages at V5 and Visit 7 (V7; 2018-2019). AS stage progression was defined as AV replacement or hospitalization, or a higher stage at V7. Associations of AS stage at V5 and AS stage progression from V5 to V7 with cardiac structure and function were assessed using multivariable linear regression. Associations of extra-AV cardiac abnormality categories with AS stage progression were assessed by multivariable logistic regression.
resultsOf 5206 V5 participants (age 75±5 years, 40% men), AS stages A and B at V5 were associated with greater left ventricular wall thickness, mass, and filling pressure measures at both V5 and V7 compared with Stage 0. Among 1562 participants with assessable AS stage at V7, AS stage progression occurred in 370 and was associated with greater worsening of these measures (all
conclusionsEarly AS stages are associated with greater left ventricular mass and diastolic dysfunction, and AS stage progression is associated with worsening of these measures. The presence of both left ventricular and left atrial extra-AV abnormalities is associated with a greater likelihood of early AS stage progression.
