Figure 2.

Box (median ± interquartile ranges) and whiskers (10th and 90th percentiles) of the total serum levels of (A) IgA, (B) IgG, and (C) IgM in the peripheral blood of non‐pregnant women (n = 35) and pregnant women (n = 43) during the third trimester of pregnancy, on the day of delivery within 15 min after placental expulsion, and during the postpartum period at least 6 wk after delivery. The gray area indicates the range of normal values. There was one missing value for IgA in the pregnant women group. Differences between groups were tested using analysis of variance (ANOVA) or the Friedman test. *P‐value <0.05; **P‐value <0.01; ***P‐value <0.001
