Fetal Loss Induced by aPg, aβ2GPI, and Absorbed aPg

Group	Na	N Resorbedb	% Resorbed	p value (Fisher’s exact test)
Control	75	4	5.33
aPgc	127	27	21.26	p = .001 vs. control
aβ2GPId	65	12	18.46	p = .01 vs. control
aPg-absd	106	13	12.26	p < .05 vs. aPg

^aN: number of fetuses observed.

^bN resorbed: number of resorbed fetuses.

^caPg: mouse IgG anti-P. gingivalis W83.

^daβ2GPI: mouse IgG anti-β2-glycoprotein I.

Control mice were administered IgG from sham-immunized (alum alone) mice.
