Erratum: Osteoarthritis: MRI detects OA-like features 'in absence of OA' (Nature Reviews Rheumatology DOI:10.1136/annrheumdis-2012-201933)

摘要

Rheumatoid factor (RF) is included in classification criteria for rheumatoid arthritis (RA), and the presence of this antibody is routinely tested for in the diagnosis of the disease. Although most patients with RA will eventually test positive for RF, whether levels of RF in those who do not have RA are associated with the risk of developing the disease is unclear. Research conducted as part of the Copenhagen City Heart Study has now shown that individuals in the general population who have elevated plasma levels of RF have up to a 26-fold increased risk of developing of RA long-term.
