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.
