Postoperative outcome at 1 year in the study population and comparison of outcomes between RYGB and SG groups
| Variable | ALL (n=760) | RYGB (n=259) | SG (n=501) | p-value |
|---|---|---|---|---|
| Weight, kg | 94.79 (19.00) | 96.79 (17.00) | 92.79 (17.00) | 0.0006 |
| BMI, kg/m2 | 32.82±5.76 | 33.59±5.40 | 32.42±5.90 | 0.002 |
| WL, % | 28.02±11.89 | 26.82±11.30 | 28.64±12.15 | 0.045 |
| EWL, % | 62.56 (33.49) | 58.06 (30.46) | 65.55 (26.59) | 0.007 |
| >50% EWL | 523 (68.82) | 169 (65.25) | 354 (70.66) | <0.0001 |
| EBMIL, % | 62.56 (33.49) | 58.06 (30.46) | 65.55 (26.59) | 0.007 |
Data are shown as mean ± standard deviation or median (interquartile range) for continuous variables and as number (percentage) for categorical variables
p-values refer to the comparison between RYGB and SG groups with the use of an independent t test or Mann–Whitney U test for continuous variables and Chi-square test with Fisher’s correction for categorical variables
Embolden p-values indicate statistically significant result
