FIGURE 1.
Vaginal bacterial community structures in patients undergoing IVF over 3 sampling intervals. The relative abundance of each taxon is represented by a different color. The sequential samples obtained from each subject are represented in a group, with sample A collected at baseline, B just before egg retrieval, and C just before embryo transfer. Subjects who did not undergo prophylactic azithromycin treatment are marked with a black bar labeled “NA,” and those receiving azithromycin are marked with a gray bar labeled “AZ.” Within each of these groups, subjects who did or did not become pregnant are annotated. According to Linear discriminant analysis Effect Size analysis, no specific taxa were associated with azithromycin treatment or pregnancy. IVF = in vitro fertilization.
