a Representative photomicrographs of piriform cortex-amygdala immunostained for IBA1 (red) to identify microglia and counterstained with DAPI (blue) to identify cell nuclei. b, c Geometric mean ratio (GMR) (dot) of the mean density of IBA1+ cells in various brain regions of animals intoxicated with DFP relative to Veh at 1, 3, 7, 14, and 28 DPE with 95% confidence intervals (bars) in males (b) and females (c). The y-axis is shown as a log-scale. Confidence intervals that do not include 1 (the gray horizontal line) and are shaded blue indicate a significant difference in the density of IBA1+ nuclei between DFP and Veh after FDR correction
