Figure 4.

¹⁸F‐FDG PET/CT results of lean vegan donors vs obese metabolic syndrome patients and posttreatment changes. Shown are PET/CT results comparing obese metabolic syndrome patients with lean vegan FMT donors at baseline and treatment‐induced change after either autologous or lean vegan‐donor FMT. Data are depicted as means with SDs. P<0.05 was considered significant. Auto FMT indicates autologous fecal microbiota transplantation; Donor FMT, lean vegan donor fecal microbiota transplantation; FDG, fluorodeoxyglucose; MetS, obese omnivorous metabolic syndrome subjects; PET/CT, positron emission tomography/computed tomography; t=0/2w, time point 0/2 weeks; TBR Max, maximum target‐to‐background ratio; Vegans, lean vegan fecal microbiota transplantation donors.
