Table 1. Expression profiles of the four phenotypes.

Expression profile of the set of genes associated with a phenotype. Phenotype of samples ((preterm labor (P L); Preterm non-labor (P NL); Term labor (T L); Term non-labor (T NL)). Number and percent of samples of particular phenotype identified by each of the expression profiles associated with a particular phenotype.

Expression profile	Phenotype
	P L (n = 34)	P NL (n = 55)	T L (n = 38)	T NL (n = 56)
P L	16 (47%)	11 (20%)	8 (21%)	3 (5%)
P NL	2 (6%)	9 (16%)	7 (18%)	4 (7%)
T L	1 (3%)	1 (2%)	4 (11%)	1 (2%)
T NL	15 (44%)	34 (62%)	19 (50%)	48 (86%)
