Figure 3From: Expression and functional properties of antibodies to tissue inhibitors of metalloproteinases (TIMPs) in rheumatoid arthritisAntibodies against TIMPs in patients with erosive or nonerosive rheumatoid arthritis (RA) and in controls. The presence of antibodies against tissue inhibitors of metalloproteinases (TIMPs) was defined as absorbance, as measured on ELISA, of (a) blood or (b) synovial fluid samples above 2 standard deviations of the mean of the control groups consisting of blood donor samples (n = 62) and synovial fluids from patients with joint trauma (n = 21).
