CRP and rheumatoid arthritis: When patients were divided according to the diagnosis, we observed that RA patients showed a reduction of DAS28-CRP, VAS-pain, and GH at all time points (p < 0.0001 for all comparisons), while PsA patients exhibited a reduction of DAPSA-CRP at all time points (p < 0.05 for all comparisons) and of VAS-pain at T3 (p = 0.01) and T6 (p = 0.04) (Supplementary Table 1).
