Distribution of the different leukocyte subsets in non-pregnant and pregnant animals.

Values are expressed as median (Q1–Q3). Due to technical problems, WBC’s of only 2 NP BBDP rats were available. Abbreviations: NP = non-pregnant, d10 = sacrificed at day 10 of pregnancy, d18 = sacrificed at day 18 of pregnancy. *: significantly different from non-pregnant BBDP rats (Mann-Whitney U-test, p<0.05). †: significantly different from non-pregnant W rats (Mann-Whitney U-test, p<0.05). Bold and italic displayed values indicate a slope significantly different from zero during the course of pregnancy (Linear regression test, ANCOVA; p<0.05).
