The study included almost 7,500 patients who were diagnosed with rheumatoid arthritis a chronic autoimmune disease marked by painful inflammation of the lining of the joints, and more than 37,000 people without the disease. The study was conducted between 1995 and 2006; median follow-up was just over four years with a maximum follow-up of 12 years.

She added that it "is also very clear that more research is needed to determine the mechanisms that link these two health conditions."
