Fig 3. Heatmap of metabolites in maternal plasma with at least 2-fold change and FDR < 0.1.

Inclusion criteria for the metabolites presented in this heatmap were FDR of 0.1 of less and a minimum 2-fold change in at least one comparison group between CVP and CVNP, GFP and GFP, GFNP and CVNP, and GFP and CVP mice. CVNP, conventional non-pregnant mice; CVP, conventional pregnant mice; GFNP, germ-free non-pregnant mice; GFP, germ-free pregnant mice.
