Effect of median liver stiffness on chronic heart failure by alcohol intake in the NHANES population: A cross-sectional study.
Article in Medicine, 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
While the relationship between liver stiffness and heart failure (HF) has been studied widely, alcohol-related differences in the association between liver stiffness and chronic heart failure (CHF) in the general population remains unclear. This study aimed to examine whether alcohol intake modifies the effect of median liver stiffness (elasticity) on CHF. This cross-sectional study analyzed the data of 6894 participants in the prepandemic National Health and Nutrition Examination Survey database dated from 2017 to March 2020. The exposure variable was the median liver stiffness, and the outcome was CHF. The association between median liver stiffness and CHF, overall and stratified by alcohol consumption, was explored, and interaction effects were tested. The participants' mean age was 50.13 ± 17.43 years, and the median liver stiffness was 5.00 (4.10-6.10) kPa. The prevalence of CHF was 2.99%. Liver stiffness had a significantly positive association with CHF (per 1 unit increase in liver stiffness; odds ratio [OR] = 1.04; 95% confidence interval [CI]: 1.02, 1.05). Multivariate logistic regression showed that each unit increase in liver stiffness raised CHF risk by 7% in participants with low alcohol intake (OR = 1.07; 95% confidence interval: 1.05, 1.09) but not in those with moderate or high alcohol intake. Alcohol consumption showed a significant interaction with liver stiffness (P for interaction = .01). These results were consistent in sensitivity analyses using Firth logistic regression to account for the low event rate. In this cross-sectional analysis based on self-reported CHF and an imbalanced distribution between cases and non-cases, higher liver stiffness was associated with a greater prevalence of CHF, particularly among individuals with low alcohol intake.
