All models adjusted for variables with estimates presented in the relevant columns; the final model was additionally adjusted for patients’ perception of the health risk posed by their weight because this factor confounded the association between patients’ minimum satisfactory weight loss and the outcome. In the final model, comorbidities tested (pulmonary disease, arthritis/back pain, diabetes, high cholesterol/GERD/gall bladder disease/serious liver damage) were not included if they were not statistically significant
