(A-B) The effect of early DEX treatment on placentome distribution as percentage of total numbers of placentomes in (A) females and (B) males. Data were analyzed by a full factorial model (MANOVA) with treatment, gender, and dG as type as factors, followed by a pairwise comparison (Holm Sidak) when main effects were P < .05. Data are presented as mean ± standard error of the mean (SEM). In females, the proportion of A subtypes placentomes in controls was lowest at 125 dG, whereas the proportion of B and C subtypes was highest at 125 dG (P < .05). This was similar in the DEX groups (MANOVA main effects: dG P < .001, type P < .05; interaction: dG × type P < .05). In males, the highest proportion of A subtypes was found at 50 dG, whereas the proportion of B subtypes was highest at 125 dG (P < .05). At 125 dG, DEX increased significantly the proportion of C subtypes compared to controls (P < .05). DEX indicates dexamethasone; dG, days of gestation.
