Risk factors and development of a predictive model for frailty in patients with heart failure.
Article in American journal of translational research, 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
objectivesTo identify factors influencing frailty in patients with heart failure (HF) and develop a predictive model for clinical use.
methodsA retrospective analysis was conducted on 350 HF patients at Shanghai Baoshan District Hospital of Integrated Traditional Chinese and Western Medicine between January 2020 and December 2023. Of these, 245 patients were allocated to the modeling group (n = 245) and 105 to the validation group (n = 105). In the modeling group, 135 patients were frail and 110 were non-frail. In the validation group, 47 patients were frail and 58 were non-frail. Logistic regression analysis was used to identify factors associated with frailty, and a nomogram was developed and validated to predict frailty risk.
resultsMultivariate logistic regression analysis identified the following independent risk factors for frailty: fall history (OR: 0.101, 95% CI: 0.043-0.242, P < 0.001), advanced age (OR: 0.877, 95% CI: 0.828-0.928, P < 0.001), female sex (OR: 2.925, 95% CI: 1.294-6.613, P = 0.010), low hemoglobin levels (< 12 g/dL; OR: 2.547, 95% CI: 1.816-3.573, P < 0.001), and diabetes (OR: 3.202, 95% CI: 1.559-6.577, P = 0.002). Using these five variables, a nomogram was constructed to predict frailty risk, demonstrating an AUC of 0.822 (95% CI: 0.771-0.907).
conclusionFall history, advanced age, female sex, low hemoglobin levels, and diabetes are significant independent risk factors for frailty in HF patients. The nomogram prediction model demonstrated strong predictive performance, with high accuracy and clinical applicability.
