FIGURE 2.

Group differences in bacterial groups measured by FISH-FLOW (log₁₀ cells/g wet feces) at D28 of the intervention using probes: Total bacteria (Eub I-II-III) (A) and Bifidobacterium spp. (Bif164) (B) in 92 adults (n = 23 per group). Values are mean and (SE) (all points) expressed as log₁₀ cells/g wet feces. ANCOVA was used to calculate intervention effect employing intervention as a fixed factor, D28 values as the dependent variable, and D0 values, sex, and PHQ-9 and GAD-7 scores as covariates. Results that are statistically significant between interventions are displayed by specified P values. Abbreviations: 2’FL, 2’fucosyllactose; OF, oligofructose; OF/2’FL, oligofructose/2’fucosyllactose.
