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: Cognitive frailty (CF) is a geriatric syndrome involving both physical frailty and cognitive impairment, increasing vulnerability to adverse health outcomes. However, practical prediction models integrating easily accessible, modifiable risk factors for community settings are lacking. This study aimed to develop and validate a predictive model for CF in community-dwelling older adults. Methods: A cross-sectional study was conducted from September 2022 to May 2024 in Pudong New District, Shanghai, with 979 participants aged 60 and above. Data on sociodemographic characteristics, behavioral factors, nutritional status, sleep quality, depression, as well as lifestyle, health-related factors, physical frailty, and cognitive function were collected through questionnaires administered to older adults, with 20 indicators analyzed. The population was divided into a 7:3 ratio for training and validation. LASSO regression and multivariate logistic regression identified risk factors, and a nomogram prediction model was developed. Model performance was evaluated using ROC curves, calibration curves, and decision curve analysis (DCA). Results: Of the 979 participants, 31.1% were diagnosed with CF. Seven predictors, including marital status, smoking, Timed Up and Go test (TUGT), depression, sleep quality, nutrition, and medication count, were identified to construct the model. Together, these variables provide a comprehensive assessment of the risk of cognitive frailty in older adults. The model exhibited good predictive performance, with AUC values of 0.753 and 0.733 for the development and validation sets, respectively. The Conclusion: Community-dwelling older adults have a higher incidence of cognitive frailty. This study developed an effective, low-cost, and non-invasive model with promising predictive capabilities that can be used as a screening tool to identify community-dwelling older adults at high risk for cognitive frailty in clinical practice. This model is expected to assist healthcare professionals in improving the effectiveness of prevention of cognitive frailty in community-dwelling older adults.
