Measurements of fetal growth at gestation day 21. Measurements of fetal length and weight at gestation day 21 are presented for males (a) and females in (c). Body composition was measured by magnetic resonance in randomly selected, pooled subsets of fetuses (n = 3/sex/dam) for males (b) and females (d). Data are presented as mean ± standard error and were analyzed by Dunn’s post-test for fetal weight, lean body mass, and fat. Fetal length and Fat to LBM ratios were analyzed by Dunnett’s post-test within a two-way ANOVA for all other endpoints. *p < 0.05 vs. A + Q. Specific p values between groups are presented for clarity. Abbreviations: air + quiet (A + Q), air + noise (A + N), ozone + quiet (O3 + Q), ozone + noise (O3 + N), lean body mass (LBM)
