Purpose/Significance To construct an integrated screening model for chronic obstructive pulmonary disease(COPD)， and to provide a supplementary tool for patients unable to cooperate with pulmonary function test(PFT). Method/Process Based on chest X-ray images and clinical routine data of 15 414 patients，an integrated model is constructed. The performance of the model is evaluated by indicators such as AUC，and a comprehensive analysis is conducted in combination with the calibration curve，decision curve and SHAP value. Result/Conclusion The integrated model combines the advantages of different algorithms，and the overall perfor.mance of COPD screening is superior. It is expected to provide a reliable supplementary screening tool for patients urable to cooperatewith PFT.
