Correlation between faecal microbial abundance and serum cobalamin, folate, cholesterol, and triglycerides. Circos plot illustrating positive correlations (r ≥ 0.6, connecting red lines) and negative correlations (r ≤ −0.6, connecting blue lines) performed using multiblock sparse partial least squares discriminant analysis of the serum concentrations of cobalamin, folate, cholesterol and triglycerides, and relative abundance of faecal microbes at study inclusion (baseline concentrations, circumferential grey line), when feeding a diet without (−PD, circumferential blue line) or with 10⁹/kg Enterococcus faecium NCIMB 10415 (+PD, circumferential orange line).
