    Modelling of biological age in stable and acute exacerbations of chronic obstructive pulmonary disease by Yujiao Wang, Ting Mu, Yufen Fu, Yuxin Wang, Guoping Li

    Published 2025-08-01
    “…The dataset was partitioned into training and validation sets at a 7:3 ratio, and LASSO regression was applied to refine the model's variable composition. To assess the ability of different variables to discriminate current disease status, we developed the initial model and three subsequent models, with the following variables added in the new model: Chronological age (CA), BA, and biological age acceleration. …”
