Canadians with Rheumatoid Arthritis
“The CATCH study importantly benefits the future generations of those with RA, but has also has had a very personal positive impact for me. When I was first diagnosed with RA, I was extremely frightened and fearful of my future… My disease is now well managed and I am certainly more positive and not nearly as fearful of my future.”
