FMc Detection and Concentration	Unadjusted Model			Adjusted Model
FMc Detection and Concentration	Vaginal Delivery (N=24)	Cesarean Delivery (N=12)	95% CI	Vaginal Delivery (N=24)	Cesarean Delivery (N=12)	95% CI
Likelihood of post-delivery FMc detection (OR)	Ref	7.0	1.4-34.4	Ref	8.8^*	1.6-47.6
Detection rate ratio of post-delivery FMc (DRR)	Ref	0.34	0.04-2.6	Ref	14.7^†	3.2-66.8

OR, odds ratio; CI, confidence interval; FMc, fetal microchimerism; DRR, detection rate ratio;

Logistic regression model adjusted for total number of cell equivalents tested, gravidity, and gestational age at delivery.

^†

Negative binomial regression model adjusted for total number of cell equivalents tested, gravidity, gestational age at delivery, and whether fetal microchimerism was detected in the pre-delivery sample.
