Correlation of bacterial taxa with iron status. Heatmap of Spearman’s correlation between iron parameters and bacterial taxonomic levels of all mice combined from four experiments. Red indicates a negative and green a positive correlation (color intensity reflective of Spearman’s r). a p_ = phylum, b c_ = class, c o_ = order, d f_ = family, e g_ = genus, f s_ = species. *p < 0.0001 for the Spearman’s correlation
