Extended Data Fig. 7: Correlations between relative abundance of bacterial taxa and concentrations of the aromatic lactic acids at each sampling point in the CIG cohort.

a, Spearman’s rank correlations between relative abundance of faecal bacterial genera (average relative abundance > 1%) and faecal concentrations of the aromatic lactic acids (ILA, PLA and 4-OH-PLA) at each sampling point. b, Spearman’s rank correlations between relative abundance of faecal Bifidobacterium species (average relative abundance > 0.1%) and faecal concentrations of the aromatic lactic acids at each sampling point. Infant-type Bifidobacterium species is the sum of the relative abundances of B. longum, B. breve, B. bifidum and B. scardovii. For both panels statistical significance was evaluated by uncorrected p-values (two-sided tests) indicated by asterisks with *p < 0.05, **p < 0.01, ***p < 0.001 and ****p < 0.0001.
