FIGURE 7.

Group differences in gastrointestinal scores for stool consistency as per the Bristol Stool Form Scale (A) and Stool Frequency (B) observed at last week of intervention (D22–D28 average) in 92 volunteers (n = 23 per group). Mean and SE (all volunteer points). ANCOVA was used to calculate intervention effect employing intervention as a fixed factor, final week D22–D28 average values as the dependent variable, and run-in week 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.
