American Heart Association's Life's Simple 7 for cardiovascular health assessment among Iranian adults: a national cross-sectional study from STEPwise approach to non-communicable diseases risk factor surveillance (STEPS) survey 2021.
Article in BMJ open, 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
objectiveTo assess cardiovascular health (CVH) metrics using the American Heart Association's Life's Simple 7 (LS7) tool as a comprehensive measure of several metabolic and behavioural risk factors for cardiovascular diseases.
designCross-sectional study, nationally representative Iran STEPwise approach to non-communicable diseases risk factor surveillance (STEPS) survey 2021.
settingIran, 2020-2021.
participants25 202 adult individuals aged 25 years and older participated in the STEPS survey. OUTCOME MEASURES: Using the LS7 framework, seven factors were assessed: current smoking, body mass index (BMI), physical activity level, modified healthy diet score components, total cholesterol, blood pressure and fasting plasma glucose (FPG). Each factor was categorised into three levels of poor, intermediate and ideal, according to the LS7 methodology.
resultsThe study participants had a sex distribution of 55.5% females. The findings revealed a high prevalence of ideal levels of smoking (80.1%; 95% CI 79.3 to 81.0), total cholesterol (69.4%; 95% CI 68.5 to 70.4) and FPG (61.0%; 95% CI 60.0 to 62.1). BMI and blood pressure were ideal in about one-third of the population (33.0%; 95% CI 32.1 to 34.0, and 30.5%; 95% CI 29.6 to 31.4, respectively). However, only 13.3% (95% CI 12.6 to 14.0) of participants achieved ideal levels of physical activity, and a mere 0.4% (95% CI 0.3 to 0.6) adhered to an ideal healthy diet. Modest disparities in CVH metrics were observed across provinces and between two sexes. Ideal CVH status was significantly associated with lower risks of major diseases such as ischaemic heart disease, diabetes and chronic kidney disease.
conclusionsDespite favourable scores in some CVH metrics, critical gaps in diet and physical activity highlight the need for intensive public health efforts to enhance CVH in Iran. The study emphasises the urgency of implementing region- and sex-specific public health policies.
