Effect of prebiotic supplementation depending on the dietary calcium phosphate background. A Partial redundancy analysis (pRDA) for the explanatory variable of supplementation (i.e., GOS, inulin, or control) (corrected for experiment) in the high-CaPi diets: Hca (yellow squares), HcaGOS (blue squares), HcaInu (red squares). B Partial redundancy analysis (pRDA) for the explanatory variable of supplementation (i.e., GOS, inulin, or control) (corrected for experiment) in the low-CaPi diets: Lca (yellow circles), LcaGOS (blue circles), LcaInu (red circles). Sample labels for experiment 1 and experiment 2 (Fig. 1F) contain an asterisk (*) or are empty, respectively
