Association of the De-Ritis (AST/ALT) ratio with coronary heart disease prevalence and all-cause mortality in U.S. adults: a national health and nutrition examination survey analysis.
Article in Journal of cardiothoracic surgery, 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
backgroundCoronary Heart Disease (CHD) is a leading cause of mortality worldwide. The De-Ritis ratio has not been fully elucidated for its value in cardiometabolic risk assessment. This study aimed to evaluate the association of De-Ritis ratio with CHD prevalence and all-cause mortality in a large, nationally representative sample.
methodsThis study utilized a cross-sectional and prospective cohort design, with data sourced from the U.S. National Health and Nutrition Examination Survey (NHANES). We employed weighted multivariate logistic regression models to assess CHD prevalence and weighted Cox proportional hazards regression models to analyze all-cause mortality. The primary exposure was the De-Ritis ratio, categorized into quartiles. The outcomes were self-reported CHD status and mortality status confirmed via linkage to the National Death Index.
resultsA total of 8,068 participants were included in the prevalence analysis, and 8,063 in the mortality analysis. After full adjustment for confounding factors, participants in the highest quartile (Q4) of the De-Ritis ratio had significantly higher odds of CHD prevalence compared to those in the lowest quartile (Q1) (odds ratio [OR] = 5.01, 95% confidence interval: 2.89-8.69, P < 0.001). In the prospective analysis, the Q4 group had a 58% significantly increased risk of all-cause mortality compared to the Q1 group (hazard ratio = 1.58, 95% CI: 1.12-2.22, P = 0.010).
conclusionAn elevated De-Ritis ratio is independently and robustly associated with higher CHD prevalence and increased risk of all-cause mortality. This suggests that De-Ritis ratio may be a valuable and cost-effective biomarker for enhancing CHD risk stratification.
