TABLE 4.

Significant bacterial OTUs in third trimester in PTB vs. term samples.

OTU	Genera	Log fold change	Adj. P-value	DiGiulio	Romero	Hyman	Callahan	Stout
Otu4172	Lactobacillus	−8.00E-09	9.06E-16	Reported	Reported	Reported
Otu868	Gardnerella	0.11	3.24E-04	Significant	Reported		Significant
Otu1238	Clostridium sensu stricto	0.03	1.58E-03
Otu10429	Aerococcus	0.02	1.64E-02	Reported
Otu22110	Lactobacillus	0.11	2.50E-02	Reported	Reported	Reported

For each OTU we show the internal OTU label, the genera label, log fold change between preterm and term models (where positive values show a higher change in preterm), the adjusted p-value by FDR (see section “Materials and Methods”) for the model and whether the taxa were “Significant” or “Reported” in the original cohorts. “Significant” represents a reported significant difference between term and PTB abundance. “Reported” represents abundance measurement reported in the original cohorts in the original papers.
