The change of microbial diversity for each type. (a) Boxplot of richness. In the Type 1 group, the richness does not show significant differences between any of the collection time points, but the spread of richness decreases over the three collection times. In the Type 2 group, the richness significantly differed between SB and D28 (P = 0.032). (b) Boxplot of Shannon diversity index. In the Type 1 group, the Shannon diversity index does not show significant differences between any of the collection time points. In the Type 2 group, the Shannon diversity index significantly differs between SB and D7 (P = 0.018)
