Extended Data Fig. 6. Scatterplot representations of the abundance of a) Bradyrhizobium and b) Burkholderia in respect to sequencing run batch effects and c) vaginal lactobacilli and d) vaginosis bacteria in respect to the mode of delivery found during 16S amplicon sequencing.

In a & b Numbers in brackets indicate the number of samples sequenced in a given run. Values of zero are not shown on the logarithmic axis. c,d) Comparisons between modes of delivery were performed by Mann-Whitney U tests, where values below 1% are regarded as 0% (not biologically relevant). * P < 0.05, *** P < 0.001.
