Differences in risk factors associated with the initiation and progression of mitral annular calcification in asymptomatic individuals.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Mitral annular calcification (MAC) is hypothesized to be a representation of atherosclerosis and is associated with adverse outcomes. However, the pathophysiology and risk factors associated with MAC development are not fully understood. Using the KOrea Initiatives on Coronary Artery (KOICA) registry, 738 asymptomatic individuals who underwent health screening with echocardiography and serial cardiac computed tomography (CT) were included for analysis. MAC was identified on CT, and the severity was quantified using Agatston units (AU). Risk factors associated with prevalent MAC and the rate of MAC progression were identified using multivariable regression models. On initial CT, 52 (7.0%) participants showed prevalent MAC, and in this group the median MAC progression rate was 3.4 AU/year (interquartile range: 0.2-14.7) during a median interscan duration of 36.4 months. Factors associated with prevalent MAC were older age (p < 0.001), higher body-mass index (p = 0.04), diabetes (p < 0.01), higher systolic blood pressure (p < 0.01), and higher left atrial volume index (p = 0.02). Meanwhile, factors associated with faster MAC progression were initial MAC severity (p < 0.001), male sex (p < 0.01), and higher serum phosphate (p < 0.001). Traditional atherosclerotic risk factors have an important role in the initial process of MAC development. The association between left atrial volume index and prevalent MAC further suggests the implication of elevated left ventricular filling pressure in MAC initiation. Conversely, initial MAC severity and mineral metabolism were found to be major determinants in the later phase of MAC progression.
