Methods: 239 diabetic inpatients with SARS-CoV-2 infection admitted to the Second Affiliated Hospital of Chongqing Medical University from December 2022 to January 2023 were analyzed retrospectively. The relevant data of the patients was collected by the electronic medical record system. The patients were divided into a death group and a survival group, and the relevant candidate factors were screened using univariate logistic regression analysis, and then the prediction model was constructed by multi-factor logistic regression analysis. The model was internally verified by the Bootstrap method, and the performance of the model was evaluated by the calibration curve and DCA curve. Results: Through logistic regression analysis, five factors were inclu展开更多
