研究目的:

收集2型糖尿病住院患者的电子病历数据,建立了基于机器学习算法的DR发生风险的预测模型。并探讨可能影响糖尿病视网膜病变发生的危险因素,希望为临床上糖尿病视网膜病变的预防和管理提供依据。  

Objectives of Study:

To collected electronic health record data from hospitalized patients with type 2 diabetes, to establish the prediction model for future risks of DR based on machine learning (ML) algorithm. To explore the risk factors that may affect the occurrence of DR and to provide a basis for further studies concerning with prevention and management of DR.
