Association of the gut microbiota composition with serum ferritin and executive function in women. (a-c) Volcano plots of the gut microbiota associated (p adjusted < 0.05) with serum ferritin (a), TDS (b), and PVF (c) in women as calculated by ANCOM-BC from shotgun metagenomic sequencing, adjusting all three models for age and BMI; and for years of education in TDS, and PVF models. Only the microbial species associated with serum ferritin, TDS (b) and serum ferritin, and PVF (c) are shown. The log2 fold change of the association with a unit change in the ANCOM-BC-transformed variable values and the log10 p values adjusted for multiple comparisons using a sequential goodness of fit were plotted for each taxon. Significantly different taxa are colored according to phylum. TDS, total digit span; PVF, phonemic verbal fluency; BMI, body mass index.
