Figure 2From: Long-term clearance from small airways in subjects with ciliary dysfunctionThe mean retention of 6 μm particles (Dae) in percentage of deposition in six subjects with PCD and ten healthy controls using an extremely slow inhalation flow, 0.05 L/s. The bars show the SD of the mean. Significant difference a) p < 0.001, b) p < 0.005, c) p < 0.01 comparing retention between the two studied groups.Back to article page
