Sequence diversity and coverage estimations for bacterial 16S rRNA gene analysis from uterine samples.

aNumber of operational taxonomic units (OTUs) found within each sample.bH′ (Shannon-Weaver Index of diversity) indicates species richness, considering the abundance of individual taxa. A higher number indicates more diversity.cChao1 is a non-parametric estimator used to predict species richness (the total number of OTUs present) in each sample based on distribution of singletons and doubletons.dNumber of sequences for used for comparative analysis.e%Coverage is calculated to estimate the representation of the phylotypes in the samples.
