Table 4 Multivariate logistic regression analysis of factors associated with the presence of early rheumatoid arthritis

From: Patients with early rheumatoid arthritis exhibit elevated autoantibody titers against mildly oxidized low-density lipoprotein and exhibit decreased activity of the lipoprotein-associated phospholipase A2
