Search
We searched these databases using two groups of search terms: (“vaginal microbiome” or “vaginal microbiota” or “pregnancy”) and (“16S ribosomal RNA” or “16S rRNA” or “whole genome sequencing”). For example, in PubMed, ((((vaginal microbiome) OR (vaginal microbiota))) AND pregnancy) AND ((16s ribosomal rRNA) OR (16s rRNA) OR (whole genome sequencing) OR (metagenomic)) were entered in the search window with the display option ‘best match’. Limitations of publication date as ‘10 years’, species as ‘humans’, and language as ‘English’ were used (Appendix S1 ).
