Figure 4. Pregnancy outcomes grouped according to the balance of Lactobacillus abundance and pathological bacteria abundance in the endometrium of patients not given antibiotics (n=23). In patients not given antibiotics (n=23), a trend (p=0.057) toward greater proportions of pregnant women (13/16: 81.2%) in the High L + Low PB group was observed, whereas a trend (p=0.057) towards greater proportions of nonpregnant women (3/4: 75%) in the Low L+ High PB group (p=0.057) was observed (Fisher’s exact probability test, one-tailed test). *High L: Group with high abundance of Lactobacillus, Low L: Group with low abundance of Lactobacillus, High PB: Group with high abundance of pathological bacteria, Low PB: Group with low abundance of pathological bacteria.
