Population attributable risk of traditional, under-recognised and female-specific factors for heart failure in women.
Article in Heart (British Cardiac Society), 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
backgroundHeart failure (HF) imposes a major health burden on women. While traditional (well-established) risk factors are well studied, less attention has been given to psychosocial, environmental and female-specific reproductive risk factors. This study quantifies the contribution of these risk domains to incident HF in women.
methodsWe included 233 125 women from the UK Biobank with a median follow-up of 13.7 years. 22 risk factors were grouped as well-established (eg, hypertension), under-recognised (eg, depression, socioeconomic deprivation) or female-specific (eg, early age at menopause, parity). Cox regression models and population attributable fractions (PAFs) were used to estimate HF risk and burden. Analyses were stratified by age and obesity.
resultsA total of 6077 women developed HF. The overall PAF for all risk factors was 66.0%. Hypertension had the largest individual contribution (PAF 25.3%). Well-established, under-recognised and female-specific risk factors accounted for 46.0%, 25.5% and 15.5% of HF cases, respectively. Chronic inflammatory diseases, early age at menopause and early age at first birth were key reproductive drivers. Age-stratified analyses showed the highest HF burden in women aged 55-59 years (PAF 70.0%).
conclusionA combination of modifiable, psychosocial, environmental and reproductive risk factors accounts for two-thirds of HF cases in women. Tailored, life course-oriented prevention strategies are essential to reduce this burden.
