Alpha and beta diversity in iFOBT, fresh and archived samples. a Shows a boxplot of the number of observed OTUs in each sample group. b and c Shows boxplots of the Inverse Simpson index (b) and Shannon (c) index in fecal immunochemical tests (iFOBT samples, fresh fecal samples and fecal samples archived for approximately 16 years. The indexes are based on rarefied OTU data to minimize the impacts of uneven sampling. The Bray-Curtis dissimilarity index for comparisons of groups are shown (d)
