Fig. 1From: Distinct fatty acid signatures in infrapatellar fat pad and synovial fluid of patients with osteoarthritis versus rheumatoid arthritisDiscriminant analysis depicting the classification of fatty acid signatures in the studied tissues based on discriminant functions 1 and 2. With these first two functions, 98.4% of the variance was explained. IFP infrapatellar fat pad, SF synovial fluid, OA osteoarthritis, RA rheumatoid arthritis.
