Geographic Distribution
Circle area is proportional to the total number of confirmed plus clinically suspected PCD patients in each center. Centers in the same city were slightly offset to keep overlapping circles visible.
Diagnostic Method Availability
The next figure summarizes the availability status of each diagnostic method as the percentage of centers reporting each category.
