Main Findings
In this review, we explored how often GBS was reported in studies of the
vaginal microbiome during pregnancy. Methods related to GBS reporting
were compared to identify potential methodological bias. Among 45
studies, 13 (28.9%) reported GBS. However, due to the heterogeneity of
methods across study approaches, we were not able to detect any
systematic differences that appeared to enhance or hinder GBS reporting.
