研究目的:

本研究拟开展一项前瞻性、观察性临床验证研究,对既往构建的糖尿病肾病精准诊断机器学习模型进行系统评估。通过在前瞻性入组人群中并行运行模型预测结果,验证其在真实临床场景下对糖尿病肾病的诊断一致性、判别能力及校准性能。  

Objectives of Study:

This study intends to conduct a prospective, observational clinical validation to systematically evaluate the previously established machine learning model for accurate diagnosis of Diabetic Kidney Disease . By running the model prospectively in enrolled participants and comparing its predictive outcomes, this study aims to validate its diagnostic consistency, discriminative ability and calibration performance for Diabetic Kidney Disease in real clinical settings.

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

All data were obtained from the hospital electronic medical record system and laboratory information system. The data were extracted by designated personnel and entered into a secure, password-protected electronic database. To ensure data quality, double independent data entry combined with logical consistency checks was performed for validation. Missing values and outliers were verified and traced accordingly.
