Incidence and risk factors for cardiovascular mortality in Iranian adults: Findings from a 10year Yazd Healthy Heart Project Study.
Article in ARYA atherosclerosis, 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
backgroundCardiovascular disease (CVD) is the leading cause of death worldwide, with a growing burden in low- and middle-income countries. Given the increasing CVD mortality in Iran and the limited evidence on long-term lifestyle determinants, a cohort study is needed to examine the effects of related factors.
methodsA total of 2,000 adults, including 1,000 men and women aged 20 to 74 years, were enrolled in a population-based cohort study in Yazd, Iran, from 2005 to 2006, with a mean follow-up of 10 years. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for CVD mortality in relation to demographic, economic status, educational, and lifestyle factors.
resultsDuring follow-up, 83 CVD deaths occurred (5.4%). The mortality rate was 6.8% in men and 3.8% in women. After adjustment for hypertension, diabetes, and hypercholesterolemia, significant predictors of CVD mortality included age ≥65 years (HR = 3.63, 95% CI: 2.28-5.77), male sex (HR = 2.29, 95% CI: 1.31-3.34), and smoking (HR = 1.95, 95% CI: 1.21-3.13). In contrast, moderate physical activity was associated with a lower risk of mortality (HR = 0.38, 95% CI: 0.17-0.84), and high school education was also protective (HR = 0.49, 95% CI: 0.25-0.98). In subgroup analyses among men, age ≥65 years, moderate physical activity, and high school education remained significant predictors of CVD mortality (P < 0.05).
conclusionAge 65 years or older, smoking, and male sex increased the risk of CVD mortality in this Iranian cohort. Physical activity and higher educational attainment were associated with a reduced risk of CVD mortality.
