Fig. 4From: Direct impact of commonly used dietary emulsifiers on human gut microbiotaImpact of dietary emulsifiers on microbiota diversity. Microbiota composition was analyzed by 16S rRNA gene sequencing and alpha diversity was computed through QIIME2 pipeline using the evenness index (a, b) and the number of observed OTUs (c, d) during the treatment (a, c) and the post-treatment phases (b, d). Area under curve (AUC) was calculated for both increase and decrease in alpha diversity, as detailed in Figure S2 and in the “Methods” section. Data are the means ± S.E.M, with individual data points being represented (N = 3). *P < 0.05 compared to the untreated group, determined by a one-way analysis of variance corrected for multiple comparisons with a Bonferroni post-testBack to article page
