CRP and rheumatoid arthritis: After 4 weeks of elemental diet, the diet group showed significant increase in grip strength (p = 0.008), decrease in RAI (p = 0.006), and loss of weight as compared to control diet group. CRP concentrations were different between the two groups but not significant. Statistically significant correlation was observed between loss of weight and grip strength at 1 week (p = 0.009) and 4 weeks (p = 0.027) in the diet groupKey note: Elemental diet may improve some parameters in RA patients
