Fig. 1From: Mucosal and salivary microbiota associated with recurrent aphthous stomatitisComparison of mucosal and salivary microbiota between control and RAS. a The species richness estimated by Chao1 and Shannon diversity index are expressed using box and whisker plots. b PCoA plot generated using weighted Unifrac metric. The two components explained 52Ā % of variance. (unfilled symbols: control samples, filled symbols: RAS samples). c The intra- and intergroup Unifrac distances of mucosal communities were obtained using weighted metric. d Double pie charts present the mean relative abundance of dominant phyla (top 5) and genera (top 15). * denotes significant difference by Mann-Whitney U test (Pā<ā0.01)Back to article page
