(A). Saliva and stool ASVs from SPLSDA that were differentially abundant between children with high and low threshold peanut allergy were correlated with saliva and stool SCFA levels, respectively. Significant correlations (FDR≤0.05) are shown. (B). The relative abundance of Veillonella nakazawae correlated with butyrate and propionate in saliva and was also significantly different between the high threshold, low threshold, and not peanut allergic groups. Wilcoxon test P values are shown. (C). The relative abundance of Bacteroides thetaiotaomicron correlated with butyrate in stool and was also significantly different between the high threshold, low threshold, and not peanut allergic groups. Wilcoxon p values are shown.
