FIGURE 4

Time courses of responses in inflammatory histopathological features to dust instillation. The vertical axis is the average semiquantitative severity score. Dots indicate time points that are statistically different from matched controls (p ≤ .05) in post hoc testing without multitest correction. The scores for the unexposed controls for all conditions and experiments were combined. Dusts are indicated at the bottom of the plot, con (PBS control), Ir8 (Camp Victory 2008 dust collection), Ir9 (2009 Camp Victory dust collection), Ku (Camp Buehring dust), NIST (U.S. urban dust), and silica (silica dust). The numbers below the dust identifiers indicate amount of dust instilled (mg/kg bw). Dust identifiers in black indicate results from the time course experiment, and gray identifiers indicate results from the comparative study.
