Gene Set Enrichment Analysis, Pr vs. NPr.

#	Gene sets	Normalized enrichment score	Normalized p-value	False discovery rate Q-value
1	Interferon signaling	3.15	<0.001	<0.001
2	Cytokine signaling in immune system	3.08	<0.001	<0.001
3	Interferon gamma signaling	3.05	<0.001	<0.001
4	Interferon alpha beta signaling	2.97	<0.001	<0.001

Gene expression was measured with a whole-genome microarray and analyzed by Gene Set Enrichment Analysis. Listed are the top 4 positively enriched gene sets in healthy Pregnant (Pr) compared to Non-Pregnant (NPr).
