Epidemiology and Mortality of Valvular Heart Disease in Brazilian Adults: Findings from the ELSA-Brasil Cohort.
Article in Arquivos brasileiros de cardiologia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMost of the current evidence on valvular heart disease (VHD) comes from high-income countries. Access to treatment and the impact of VHD on quality of life may vary substantially across nations, largely due to socioeconomic differences.
objectiveThis study aimed to estimate the burden of VHD and its association with mortality in a middle-income country.
methodsWe included participants from the ELSA-Brasil cohort who underwent transthoracic echocardiography at baseline (3,267 participants; 1,539 males; mean age 60.6 ± 8.8 years) across six Brazilian states. Participants were categorized into three groups-no VHD, trace/mild VHD, and moderate/severe VHD-and their characteristics and associated factors were analyzed. P-values < 0.05 were considered statistically significant.
resultsAmong all participants, 2.4% had moderate/severe VHD (including 7 participants with prosthetic valves), and 43.6% had trace/mild VHD. The most prevalent moderate/severe VHD was mitral regurgitation, followed by aortic and tricuspid regurgitation, with 56 participants (86%) presenting isolated valvular regurgitation. Moderate/severe VHD was more common in older individuals and was associated with a higher prevalence of most cardiovascular comorbidities, but with lower obesity rates. It was also associated with greater cardiac remodeling and reduced systolic function, with phenotypic variations depending on the affected valve. Moderate/severe VHD was linked to increased 10-year mortality (HR: 3.7; 95% CI [2.17-6.31]), independent of age, sex, and hypertension.
conclusionVHD is common among community-dwelling adults in this middle-income country and increases with age. Participants with moderate/severe VHD exhibited a greater burden of comorbidities, more pronounced cardiac remodeling, worse systolic function, and substantially reduced long-term survival.
