CRP and rheumatoid arthritis: Of special interest are the correlations between the 5T-PROs total score and disease activity indices such as CDAI for RA (r = −0.709; p < 0.001), DAPSA for PsA (r = 0.479; p < 0.001), and ASDAS-CRP for axialSpA (r = 0.549; p < 0.001), and between 5T-PROs total score and FIQ-R for FM (r = 0.722; p < 0.0001).
