A recent systematic review of predictors of RA remission found that demographic and clinical characteristics of RA (such as male sex; young age; late-onset RA; low disease activity; RF status; ACPA status; nonsmoker status; short disease duration; mild functional impairment; low baseline radiographic damage) correlated with a higher rate of remission in patients with RA [10]. This evidence concerns the gene PRTN3 and rheumatoid arthritis.
