Lifestyle Factors and Diet-Disease-Related Knowledge: A Network Psychometric Analysis of Cardiovascular Health Literacy Among Lebanese Adults.
Article in Nutrients, 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/
objectivesDiet-disease-related knowledge (DDRK) is theorized to foster healthier lifestyles; however, the structural interconnectedness between nutritional knowledge and personal biomarker awareness is not well understood. This study aimed to identify independent predictors of DDRK and cardiovascular health (CVH) literacy among Lebanese adults using a psychometric framework.
methodsA cross-sectional convenience-sampled online survey was conducted among 406 Lebanese adults. Standard validated questionnaires were used, including the GNKQ-Section 4, GPAQ, and MEDAS. CVH literacy was computed as the total awareness of five main CV biomarkers: total cholesterol, LDL, HDL, triglycerides, and HbA1c. Data were analyzed through multivariable logistic regression and EBICglasso network analyses.
resultsOverall, the prevalence of cardiovascular (CV) biomarker unawareness was 65.5% across participants. Fully adjusted regression models showed that a continuous DDRK score was a significant factor independently associated with lower odds of CV biomarker unawareness (aOR = 0.878, 95% CI [0.824-0.936],
conclusionsDDRK shows strong conditional network associations with Mediterranean diet adherence and CVH literacy. These exploratory findings generate hypotheses for future longitudinal or interventional research.
