Extended Data Fig. 4: Correlations between individual Bifidobacterium species and faecal levels of aromatic lactates at 2 or 6 months of age.

Spearman’s rank correlation coefficients (SCC) between faecal levels of aromatic lactates at 2 or 6 months of age and individual aldh+ and aldh− bifidobacteria when detected (n = 141 at 2 months, n = 54 at 6 months). The Holm-Bonferroni method was used to adjust for multiple testing at each time point, with asterisks indicating *Padj < 0.05, **Padj < 0.01, ***Padj < 0.001.
