  1. Values are expressed as median (interquartile range [IQR]) and mean ± standard deviation. Lowercase letters indicate the difference (p < 0.05) among the adipose tissue types (Shapiro-Wilk followed by t test or Mann-Whitney). Upper case letters indicate difference (p < 0.05) among the groups, by comparison between surgical techniques, in the same type of adipose tissue (Repeated measures ANOVA, followed by the Tukey-Kramer test for parametric data; or Friedman test followed by the Dunn test for non-parametric data)
  2. FA fatty acid, VAT visceral adipose tissue, SAT subcutaneous adipose tissue, SG sleeve gastrectomy (n = 19), RYGB Roux-en-Y bypass (n = 14)
