Estimated sample richness (alpha diversity) by birth outcome; live birth (LB) versus no live birth (NLB). The observed microbial richness (Observed) and Shannon diversity index (Shannon) based on birth outcome is not significantly different (p = 0.596). Both sequencing runs were considered as separate samples so that each sample has two reported values. The color of the dots indicates the sequencing run, while the NLB black dots indicate an outlier
