- Tissues were scored semiquantitatively for histomorphological features. Prevalence indicates the fraction of examined animals displaying a histopathological feature. Bullets indicate histological observations in exposed animals that are statistically different from control at p ≤ .05 using the Kruskal-Wallis test. Daggers indicate specific conditions different from control at p ≤ .05 (uncorrected) in post hoc testing with the Wilcoxon ranks test.
