What people say about research
Don't take our word for it, here's what our past volunteers have to say.
I find the work at COERD innovative, important, and fascinating. I immediately signed up for the study once I heard about it because it's a great way to contribute to research!

I say yes to participating in research because I want to know more about my condition and how I can maintain my health and lung function.
