CRP and rheumatoid arthritis: Interestingly, the FFA levels correlated in RA patients with TJC28 (r = 0.48 and P = 0.022), CRP (r = 0.47 and P = 0.029), and DAS28 (r = 0.53 and P = 0.012) and a trend toward a positive correlation with VAS GDA (r = 0.39 and P = 0.07) and SJC28 (r = 0.41 and P = 0.06) was seen (Fig. 3).
