Patient Factors Predicting Weight Loss after Roux-en-Y Gastric Bypass

Table 3

Logistic regression analysis correlating preoperative clinical factors and successful versus unsuccessful weight loss in patients following RYGB at 1-year follow-up. Data expressed as (%) for nominal variables or mean for continuous variables. Successful EWL was defined as ≥60%; unsuccessful EWL ≤ 59%. of successful versus unsuccessful EWL. OR: odds ratio.
