Weight loss outcomes 1 year after sleeve gastrectomy according to metabolic dysfunction-associated steatotic liver disease (MASLD) stage.
| No MASLD (n = 58) | MASL (n = 38) | MASH (n = 67) | p Value | |
|---|---|---|---|---|
| Weight (kg) | 88.9 ± 17.2 a | 91.2 ± 18.5 ab | 98.7 ± 18.4 b | 0.008 |
| BMI (kg/m2) | 32.2 ± 5.9 a | 32.7 ± 6.6 ab | 35.3 ± 5.9 b | 0.007 |
| %EWL | 69.4 ± 21.8 a | 67.8 ± 23.1 ab | 57.4 ± 20.1 b | 0.004 |
| %TWL | 30.9 ± 8.8 | 30.3 ± 9.3 | 27.3 ± 9.9 | 0.079 |
Data are given as mean ± standard deviation (SD). Comparisons among groups were performed using an ANOVA test for continuous variables with a normal distribution (i.e., weight, %EWL, and %TWL), or a Kruskal–Wallis test for continuous parameters without a normal distribution (i.e., BMI), followed by a Bonferroni post hoc analysis. Statistical significance was set for a p value < 0.05. Different superscript letters denote significant differences within each row between the groups. BMI, body mass index; %EWL, percentage excess weight loss; %TWL, percentage total weight loss. %EWL at 1 year after SG was calculated by the formula (preoperative weight—weight at 1 year)/(preoperative weight—ideal weight) × 100. Ideal weight was calculated for a BMI of 25 kg/m2. %TWL at 1 year after SG was calculated by the formula (preoperative weight—weight at 1 year)/preoperative weight × 100.
