Signature 1
Source: Figure 1 and Figure 2
Description: Figure 1. Associations of the microbial taxa with long-term dietary habits and other factors from the questionnaire (n = 207 subjects). Analysis was performed for the baseline samples at taxonomic levels from species to phyla. Rows are sorted in alphabetic order. Cell color denotes the value of the linear model coefficient from the MaAsLin analysis. All significant associations (FDR adjusted p < 0.1) are marked with one of the symbols (&, #, @): “&”. Figure 2. Major changes in the gut community structure of the volunteers after following the dietary recommendations. Red branches of the cladogram denote the taxa that were increased in abundance, while the blue ones—decreased. Significance criterion: p < 0.05 in metagenomeSeq model and log10 of the effect size >2 in LEfSe method (n = 430 paired samples).
Abundance in Group 1: increased abundance in Low vegetable, fruit, grains,
