Just a curiosity question....are these centers creating their own registry? Or are they using existing registries, such as https://www.copdfoundation.org ? There seem to be a number of registries like https://ntminfo.org/ntm-registry/ and others on other continents. I guess there's money in it but I wonder what the advantages are of having multiple registries? I guess by country or continent makes sense. Maybe it's similar to having more than one net to catch fish.
