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
Background: Disability in older adults, characterized by progressive limitations in performing activities of daily living, poses a significant public health challenge in aging societies. Early identification of individuals at risk is critical for implementing targeted interventions to mitigate functional decline. However, existing prediction models often prioritize disease-related physiological indicators and overlook psychosocial dimensions, limiting their practicality and scalability in community-based settings. This study aimed to develop and validate a practicable prediction model for 1-year disability risk by integrating multidimensional indicators. Methods: A prospective community-based cohort in Beijing, functionally independent at baseline, was followed for 1 year. Disability was defined as a decline in the Barthel Index score. Potential predictors included demographic, lifestyle, clinical, physical, and psychosocial measures. The least absolute shrinkage and selection operator (LASSO) regression was used for variable selection, followed by logistic regression to construct the final model. Model performance was evaluated through fivefold cross-validation repeated 100 times, with assessment of discrimination and calibration. Results: Among 1003 community-dwelling older adults (mean age 68.4 ± 5.2 years; 58.3% female), 163 (16.3%) developed disability at follow-up. The LASSO regression identified seven predictors: age, dyslipidemia, gait speed, waist circumference, difficulty in lifting weights, appetite, and emotion regulation ability. The model demonstrated moderate discrimination, with an area under the receiver operating characteristic curve of 0.716 (95% CI: 0.712-0.720). Calibration curves indicated good overall agreement between predicted and observed risks. A nomogram was developed to facilitate individualized risk prediction in clinical practice. Conclusions: This study presents a practical disability risk prediction model incorporating physical, metabolic, and psychosocial factors. The model exhibits acceptable discrimination and calibration, supporting its potential for early screening and stratified management of community-dwelling older adults. Future multicenter validations are warranted to enhance generalizability and explore dynamic interventions targeting modifiable factors like emotion regulation and gait speed.
