Figure 3. Spearman’s correlation analyses of early gestation cervicovaginal fluid.

(A and B) OTUs and metabolites (n = 305) and OTUs, metabolites, elafin, cathelicidin, and HNE (n = 161). OTUs selected as follows: showing more than 1% average abundance; identified via LEfSe analyses as associated with spontaneous preterm birth (sPTB < 37 weeks). Only correlations with adjusted P < 0.05 are shown; scale represents correlations values: blue (negative) and red (positive).
