Preoperative BMI and Weight Loss Correlation

Study reveals a non-linear, inverted U-shaped association between preoperative BMI and optimal weight loss outcomes post bariatric surgery. Setting a BMI threshold of 42.9 is critical in predicting optimal clinical responses in patients with obesity. Quartile odds ratios and restricted cubic spline analysis support this correlation, highlighting the importance of personalized treatment strategies based on preoperative BMI levels.
