Figure 1. Mean MCC (±SD) from the right lung between 1–1.5 hours and 6–6.5 hours in 7 C57BL/6 control mice (dark bar) and 8 drug-treated C57BL/6 mice (light bars).

There was a trend toward slower clearance in the drug-treated mice, compared to controls, at 1–1.5 hours, but differences in MCC were not statistically significant. Mucociliary clearance was statistically significantly slower in the drug-treated mice, compared to controls, at 6–6.5 hours (p = 0.006).
