Fig. 2From: Benchmark of 16S rRNA gene amplicon sequencing using Japanese gut microbiome data from the V1–V2 and V3–V4 primer setsDifferences in microbial structure assessed using V12 and V34. A–D The relative composition of the indicated phyla and genera. Daggers indicate statistical significance between V12qI and V34qI (p < 0.01). Double daggers indicate statistical significance between V12qII and V34qII (p < 0.01)Back to article page
