Note for Male Smokers: The Healthy Eating Index Associated With the Risk of Subclinical Myocardial Injury.
Article in Clinical cardiology, 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
objectivesTo investigate the associations of the healthy eating index (HEI) and subclinical myocardial injury (SCMI) in different smoking statuses (current smokers, former smokers, and never smokers) based on the National Health and Nutrition Examination Survey (NHANES) III.
methodsSCMI was defined as a cardiac infarction injury score (CIIS) ≥ 10. The HEI was compared between individuals with and without SCMI across different smoking status categories. Logistic regression analysis was used to investigate the association between HEI and SCMI stratified by smoking status, as well as in subgroups defined by sex and smoking status. Restricted cubic spline (RCS) modeling was applied to assess the nonlinear relationship between HEI and SCMI risk among male participants. Logistic regression-based classification was further employed to explore the contribution of individual HEI components to SCMI risk in male smokers.
resultsA total of 7256 participants (without SCMI group: 5389; SCMI group: 1867) were included. After stratifying by smoking status, a significant difference in HEI was found between the two groups among smokers. Multivariable logistic regression analysis revealed that HEI was inversely associated with the odds of SCMI in smokers. This association was particularly pronounced in male smokers. RCS analysis revealed a negative linear association between HEI and SCMI risk in male smokers. Diet variety and saturated fats were major contributors to this relationship.
conclusionThis study demonstrated that in male smokers, HEI scores negatively correlated with SCMI risk, with diet variety and saturated fats being major contributors in the late 1980s to early 1990s.
