About

This study aims to develop and validate a prediction model for estimating the probability of inadequate weight loss one year after sleeve gastrectomy.

Full description

Inadequate weight loss (IWL) is a major problem after sleeve gastrectomy, leading to the recurrence of obesity-related comorbidities and increased risk of revision surgery. It is important to identify the high-risk individuals for IWL before surgery so that clinicians can initiate more rigorous weight monitoring and management strategies. Therefore, this study aims to develop a prediction model using preoperative clinical and laboratory data to estimate the risk of IWL one year after sleeve gastrectomy, and then validate it using two separate datasets.
