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

Table 4

Logistic regression analysis correlating preoperative clinical factors and successful versus unsuccessful weight loss in patients following RYGB at 2-year follow-up. Only significant data are presented. Data expressed as (%) for nominal variables or mean for continuous variables. Successful EWL was defined as 60%; suboptimal EWL 59%. of successful versus unsuccessful EWL. OR: odds ratio.
