Prevalence of heart failure stages in elderly population: from a community-dwelling elderly people survey.
Article in BMC geriatrics, 2025. 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) is a major public health concern in China, but there is a lack of epidemiological data on the prevalence of early-stage HF in the elderly.
objectivesThis study aimed to evaluate the prevalence of different stages of HF in individuals aged ≥ 60 years in a community-based survey.
methodsThis cross-sectional study enrolled 7,640 participants from a community. Basic demographic information, NT-proBNP, troponin T (TnT) levels, and echocardiographic data were collected. Participants were classified into four stages: Healthy, Stage A, Stage B, and Stage C. Prevalence and associated risk factors were analyzed.
resultsThe mean age was 70.2 years, with 54.5% being female. The prevalence of Stage A and B was 44.0% and 27.8%, respectively. In Stage A, hypertension was the most common risk factor (80.89%), followed by diabetes (29.75%) and obesity (18.08%). In Stage B and C, 97.2% and 88.2% had an ejection fraction ≥ 50%. The prevalence of Stage B increased with age (P < 0.001), and women had higher prevalence of Stage B compared to men (29.69% vs. 25.65%, P < 0.001). Female gender (OR 1.352, P < 0.001), older age (OR 1.096, P < 0.001), atrial fibrillation/flutter (OR 2.853, P < 0.001), and coronary artery disease (OR 1.473, P < 0.001) were identified as significant risk factors for Stage B.
conclusionsThis survey revealed a high prevalence of Stage A and B HF in the elderly, with most Stage B individuals having an ejection fraction ≥ 50%, emphasizing the need for targeted prevention and management strategies for at-risk groups.
