Dietary and lifestyle factors associated with cardiovascular disease risk: a structural equation modeling approach.
Article in BMC cardiovascular disorders, 2025. 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
backgroundCardiovascular diseases (CVDs), resulting from complex interactions among socioeconomic, behavioral, and dietary factors, remain a major global health challenge. This study utilized structural equation modeling (SEM) to assess the direct and indirect effects of these factors on CVD risk, with dietary indices-the Dietary Insulin Index (DII) and Dietary Glycemic Index (DGI)-acting as mediators, in a population from western Iran.
methodsA cross-sectional analysis was conducted on 3,452 adults aged 35-70 years from the Dehgolan Prospective Cohort Study (DehPCS). Data collected included anthropometric measurements, socioeconomic status, lifestyle behaviors, chronic diseases, and dietary indices (DII and DGI). SEM was employed to examine pathways linking latent variables (socioeconomic status, personal habits, and chronic diseases) and mediators (DII, DGI) to CVD risk. Model fit was evaluated using the Comparative Fit Index (CFI), Root Mean Square Error of Approximation (RMSEA), and χ² statistics.
resultsThe model accounted for 11% of the variance in CVD risk (R² = 0.11). Higher socioeconomic status directly reduced CVD risk (β = -0.28, p < 0.001) and chronic disease burden (β = -0.21, p = 0.002). Favorable personal habits, including physical activity and adequate sleep, were associated with reduced CVD risk (β = -0.27, p < 0.001). Conversely, higher DII increased CVD risk (β = 0.15, p < 0.001), while higher DGI was associated with a modest reduction in risk (β = -0.03, p < 0.001). Indirectly, socioeconomic status (β = 0.086, p = 0.001), personal habits (β = 0.035, p = 0.001), and chronic diseases (β = 0.047, p = 0.001) influenced CVD risk through dietary patterns.
conclusionDietary quality mediates the relationship between lifestyle, chronic conditions, and CVD risk, with socioeconomic disparities and chronic diseases amplifying this risk. Public health interventions should focus on promoting healthy dietary habits and ensuring equitable access to nutritious foods to mitigate cardiovascular risk.
