The distribution of incidence rates of cardiovascular diseases in the elderly and the relationship between dietary patterns and cardiovascular risk.
Article in PeerJ, 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
Background: Cardiovascular diseases (CVD) were leading causes of morbidity and mortality in the elderly. This study investigates the distribution of CVD incidence among older adults and examines the relationship between dietary patterns and associated risks. Methods: A retrospective analysis was conducted involving 2,568 patients aged 65 and older hospitalized between 2022 and 2024. Out of these, 298 patients were selected based on specific inclusion criteria for cardiovascular risk assessment using the China-PAR model. Participants were stratified into low-risk and high-risk groups for CVD based on a 5% threshold. Detailed dietary intake was assessed using the European Prospective Investigation into Cancer and Nutrition (EPIC) questionnaire, and blood samples were analyzed for biochemical markers. Statistical analyses including logistic regression were applied to examine dietary influences on CVD risk. Results: Ischemic heart disease was most prevalent (37.83%) among the elderly, with increased incidence in males. Higher intakes of fruits, vegetables, legumes, cereals, and fish correlated with reduced CVD risk. Conversely, consumptions of meat, edible oil, and alcohol were associated with heightened risk. The high-risk group exhibited poorer markers of cardiometabolic health and increased intake of energy, saturated fatty acids (SFA), and cholesterol. Metabolite analyses revealed elevated trimethylamine N-oxide (TMAO) and secondary bile acids in high-risk individuals. Conclusion: Higher age and male gender were associated with increased CVD risk, exacerbated by specific dietary patterns. Diets rich in plant-based foods and low in animal products and alcohol effectively reduced CVD risk factors. These findings underscore the potential of dietary interventions to improve cardiovascular health in the elderly.
