Signature 1
Source: Figure 4B, 6A, Table S3
Description: Altered genera in LF intake group (Base vs LPect). The pairwise comparison was performed using the Wilcoxon signed-rank test for statistical analysis to compare LPect and HPect effects on base period microbiota at the genus level.
Abundance in Group 1: increased abundance in LPect (Low pectin smoothie) (LF intake group)
