RYGB—Roux-en-Y Gastric Bypass, SG—Sleeve Gastrectomy, DQI-I—diet quality index international, Est—estimate of average marginal effect (AME), SE—standard error, pp value for testing the significance of AME estimates, Estpairwise, SEpairwise, Ppairwise—estimates of AME, standard error and p value, respectively, for pairwise comparisons between Placebo and Probiotic group (Placebo minus Probiotic).
