Description: Significant taxa by Wilcoxon signed-rank in paired tumor and normal tissue. Box plots representing relative abundances of taxa observed to be significantly different between tumor (orange) and adjacent normal (blue) samples by paired Wilcoxon signed-rank testing after correction for FDR.
