Values presented are means ± SDs of relative abundance percentages of participants in the almond and cracker groups at baseline and week 8 of the intervention. **Significantly different from week 8. ANCOM, analysis of composition of microbiomes; c, class; f, family; g, genus; o, order; p, phylum; s, species.
W-taxa represent the number of significant log-ratios for that taxon at the time, snack, and time × snack levels. *Denotes overall significance at a 60% cutoff, that is, at least 60% of the log-ratios were significant (i.e., P < 0.05) after adjusting for multiple testing of log-ratios using the Benjamini–Hochberg procedure. Analysis was a linear mixed model analysis within the ANCOM framework.
