Hi again, Martyn, and thanks for this post. I see it is very similar to another post you made elsewhere on our COPD.net platform, for which I was able to provide a response.
For your convenience, and ease of reference, here is a link to that conversation: https://copd.net/members/communitymember58a5d9/status/122541.
I do hope you have an opportunity to look over that conversation.
What do you think?
