Data presented as . ALT: alanine transaminase; AST: aspartate transaminase; ALP: alkaline phosphatase; GGT: gamma-glutamyl transferase; VAT: visceral adipose tissue; SAT: subcutaneous adipose tissue; SMI: skeletal muscle index; HDL: high-density lipoprotein; LDL: low-density lipoprotein; BMI: body mass index. Statical analyses were performed using repeated-measure ANOVA. Postsurgery values in the immediate and late postsurgery period were compared to the baseline using Dunnett’s test for multiple comparisons. is considered statistically significant.
