Objectives of Study: |
The purpose of this study was to construct and validate a machine learning-based model for predicting the risk of weight loss in patients after weight loss by using multicenter mixed cohort data. The specific goals include: identifying the main factors affecting weight loss and improving the accuracy of weight loss risk prediction. |
