Overview of QC-filtered samples (n = 146). a Principal coordinates analysis (PCoA) on Bray-Curtis distances. Numbers in brackets denote percent of variation explained. b Boxplot of Bray-Curtis distances for bacterial mock and stool samples. Biological variation is shown between three samples from the same individual. Technical variation examines the same sample over multiple sequencing runs
