Re: Re: Prevalence of hepatitis C virus infection in patients with rheumatoid arthritis.

No, they were trying to see if hepatitis C virus infection might be a

trigger for or lead to the development of RA, but their results don't

support that hypothesis.

I apologize if I sound ignorant, but what does this mean? Are they

saying that people with RA may have Hep C also?
