Fig. 2From: A specific synbiotic-containing amino acid-based formula restores gut microbiota in non-IgE mediated cow’s milk allergic infants: a randomized controlled trialPlots summarizing the bacterial diversity of saliva (a, c) and faecal samples (b, d) using Faith’s phylogenetic diversity and the Shannon index, respectively. The symbols and error bars show the least square (LS) means with 95% CI for treatment by time. The faecal bacterial diversity of the HBR reference group (age-matched to week 8) is plotted as well. P-values are based on a random intercept mixed model with week 8/12/26 values as outcome, stratification factor and baseline values as covariate and treatment as fixed effect: *P ≤ 0.05 and **P ≤ 0.01Back to article page
