Figure 5 demonstrates a high clinical value of SSmax, REE, ESR, CRP, and DAS-28 in the evaluation of acute and chronic RA (Table 1). DAS-28 score is a frequently adopted evaluation index for patients with RA. Lastly, we analyzed the evaluation value of DAS-28 combined with SSmax or REE in acute and chronic RA.  Figure 6 reveals that, with SSmax or REE, DAS-28 can deliver a higher value in evaluating acute and chronic RA (Table 2). The gene discussed is CRP; the disease is rheumatoid arthritis.
