Figure 6. Presence of L. helveticus was associated with an increase in butyrate and lactate faecal counts.

A. Scores plot derived from the O-PLS model using the absence (dark blue) or presence (light pink) of L. helveticus as a response predictor. The calculated scores (x axis) are plotted against the cross-validated scores (y axis). B. Loadings plot derived from the same model showing the metabolic contribution of butyrate, lactate and glucose. Metabolites pointing upwards correlate with the presence of L. helveticus.
