Table 2.

Number (%) of participants in each of the three interventions ho lost ≥ 5%, ≥ 10%, and ≥ 20% of initial weight at 1 year.

Weight Loss Criterion	Month 12
≥ 5% Loss
Non-BED Surgery	48 (81.4%)
BED-Surgery	27 (75.0%)
BED-Lifestyle	20 (40.8%)
≥ 10% Loss
Non-BED Surgery	44 (74.6%)
BED-Surgery	24 (66.7%)
BED-Lifestyle	13 (26.5%)
≥ 20% Loss
Non-BED Surgery	35 (59.3%)
BED-Surgery	16 (44.4%)
BED-Lifestyle	6 (12.2%)

Note: The proportion of participants in the BED-Surgery group who achieved a ≥ 5%, ≥ 10%, and ≥ 20% weight loss was equivalent to the proportion of participants achieving the same level of weight loss in the Non-BED Surgery group, and significantly greater than the proportion of participants achieving the same level of weight loss in the BED-Lifestyle group (95% CI). Statistically significant differences between groups are described in the text.
