The association between Trx and Lf in RA patients was also significant in males (r=0.857, p=0.014) and females (r=0.508, p<0.0001), in the subgroups with DAS28<5.1 (r=0.722, p<0.0001) and DAS28>5.1 (r=0.350, p=0.046) and the subgroup with normal CRP level (r=0.522, p<0.0001). Here, TXN is linked to rheumatoid arthritis.
