Development and validation of a machine learning-based prediction model for frailty in older adults with diabetes: a study protocol for a retrospective cohort study.

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
introductionFrailty is a common condition in older adults with diabetes, which significantly increases the risk of adverse health outcomes. Early identification of frailty in this population is crucial for implementing timely interventions. However, there is a lack of specific prediction models for frailty in older adults with diabetes. This study aims to develop and validate a prediction model for frailty in this high-risk group. METHODS AND ANALYSIS: This study uses data from the national follow-up of the China Health and Retirement Longitudinal Study (CHARLS), which range from 2011 to 2020. The study population includes older adults with diabetes aged 60 and above. Frailty is assessed using Fried's frailty phenotype. Potential predictors will be identified through a systematic review and expert consultation. Eight machine learning models will be developed to predict frailty, with model performance to be evaluated using receiver operating characteristic curves, calibration plots and internal validation through leave-one-out cross validation. Finally, the optimal model will be deployed via an electronic risk calculator with Shapley Additive Explanation-based visualisations. ETHICS AND DISSEMINATION: The CHARLS was approved by the Biomedical Ethics Committee of Peking University (approval number: IRB00001052-11015), and all participants were required to sign informed consent. This study was approved by the Medical Research Ethics Committee of the University of South China (approval number: 2023NHHL006). We will disseminate results via presentations at scientific meetings and publication in peer-reviewed journals. PROSPERO REGISTRATION NUMBER: CRD42023470933.
