EBV positive and negative RA patients showed no significant difference concerning clinical and laboratory parameters such as CRP (P = 0.313), WBC (P = 0.249), RBC (P = 0.171), PLT (P = 0.729), ALT (P = 0.200), ALP (P = 0.067), and urea (P = 0.046) except serum creatinine (P = 0.022), shown in Table 2. Here, GPT is linked to rheumatoid arthritis.
