Fig. 2From: Association of serum 25-hydroxyvitamin D (25(OH)D) levels with the gut microbiota and metabolites in postmenopausal women in ChinaDecreased bacterial richness and diversity in the Low 25(OH)D group. A Comparison of bacterial alpha diversity indexes, including Observe, Chao1, ACE, Shannon, Simpson and J. B ANOSIM was used to analyze the significant differences in colony distribution between the High 25(OH)D group and the Low 25(OH)D group (R = 0.025, p = 0.046). C PCoA revealing the bacterial communities between the High 25(OH)D group and the Low 25(OH)D group on the PCoA1 vs. PCoA2 axis (p = 0.015). D Venn diagram showing the differences in bacterial community structures between samples from the High 25(OH)D group and the Low 25(OH)D groupBack to article page
