Table IV.

Summary of ciliary function. The 3 groups of beat pattern and corresponding ultrastructural defect, ciliary beat frequency, and immotility index are displayed. The mean (95% CIs) and range for ciliary beat frequency and mean (95% CIs) for the percentage of immotile cilia (immotility index) are shown. Normal ciliary beat frequency data are taken from reference 20.
