Fig. 2From: Distinct fatty acid signatures in infrapatellar fat pad and synovial fluid of patients with osteoarthritis versus rheumatoid arthritisThe relative differences (%) in the proportions of selected fatty acids (FA) between tissues. IFP infrapatellar fat pad, SF synovial fluid, OA osteoarthritis, RA rheumatoid arthritis. The bars with negative values indicate that a FA had higher percentages in IFP than in SF, and the bars with positive values indicate higher percentages in SF than in IFP [(mol-% in SF–mol-% in IFP)/mol-% in IFP; mean + SEM]. Asterisk denotes significant difference between OA and RA (t test, p < 0.05)Back to article page
