Association between isolated minor ST-segment and T wave changes with 10 years all-cause and stroke mortality.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Minor ST segment and T wave (ST-T) abnormalities are commonly seen on the resting electrocardiograms (ECGs) of healthy individuals, but the long-term effects of these findings, particularly in the general population, have not been thoroughly assessed. As a result, our objective was to examine the link between isolated minor ST-T abnormalities in the general population and mortality from both cardiac and non-cardiac causes. The ECGs of 9035 participants within the Mashhad stroke and heart atherosclerotic disorders (MASHAD) study were evaluated. This was followed by a monitoring period of over a decade to investigate mortality results. The electrocardiograms were analyzed for ST-segment and T-wave irregularities using the Minnesota Codes classification system. Kaplan-Meier survival analysis was utilized to compare mortality rates for cardiovascular disorder (CVD), coronary heart disease (CHD), stroke, and all-cause death between cohorts with ECG alterations and those without. Individuals exhibiting isolated minor ST-T changes were predominantly female (p < 0.001), had a higher prevalence of diabetes mellitus (p = 0.031), and were more likely to be unemployed (p = 0.001). No significant differences were observed in age, marital status, educational attainment, smoking status, body mass index, dyslipidemia, and hypertension between the groups. Isolated minor ST-T abnormalities were identified as significant predictors of stroke mortality (p = 0.017). The presence of these ECG changes did not correspond to an increased risk of cardiovascular disease (CVD) or coronary heart disease (CHD) mortality. Upon adjustment for gender, employment status, and diabetes mellitus, the association between minor ST-T changes and all-cause mortality was p = 0.050. Individuals with isolated minor ST-T abnormalities were more likely to die from stroke. Therefore, it is advisable to implement preventive measures for the affected population, particularly women and individuals with diabetes, who are at higher risk of experiencing these ECG changes. Additionally, it is important to closely monitor the clinical status of those affected.
