High-fat diet score reveals total and cardiovascular mortality and identifies protein biomarkers in large cohorts.
Article in Journal of advanced research, 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
introductionThe high-fat diet (HFD) has complex health implications, shaped by the composition of macronutrients and food sources. However, existing dietary assessment tools lack the precision required for effective risk stratification.
objectivesThis study developed novel HFD scores to accurately characterize dietary patterns and examined their associations with total and cardiovascular disease (CVD) mortality, while also identifying relevant protein biomarkers.
methodsData from the UK Biobank and NHANES were utilized to develop a novel HFD scoring system incorporating both macronutrient ratios and quality indicators. Mortality associations were evaluated using Cox proportional hazards models, Kaplan-Meier analysis, and restricted cubic splines (RCS). Proteomic analysis was conducted to identify plasma proteins associated with mortality.
resultsThe unhealthy HFD score showed a linear correlation with increased total and CVD mortality. In contrast, the healthy HFD score exhibited a U-shaped relationship with CVD mortality. On a 30-point HFD scale, individuals with low total mortality risk in the UK and US should maintain scores below 15, while those with low CVD risk in the UK should aim for scores between 10 and 15. An online HFD risk calculator was developed for practical application. Proteomic analysis revealed 48 proteins linked to total mortality and 153 proteins associated with CVD mortality, with significant enrichment in immune regulation and cardiovascular pathways. Machine learning models identified key predictors, such as EDA2R and NTproBNP, which demonstrated mediation effects of 12.92% and 13.86%, respectively.
conclusionThese findings establish a precision nutrition framework that links HFD patterns, proteomic biomarkers, and mortality outcomes, offering actionable insights for clinical and public health intervention.
