[Retracted] Clinical Efficacy of Methotrexate Combined with Iguratimod on Patients with Rheumatoid Arthritis and Its Influence on the Expression Levels of HOTAIR in Serum

Figure 1

Comparison of the expression levels of serum HOTAIR and TNF-α in each group. (a, b) The expression levels of HOTAIR and TNF-α in serum of patients in the CG and the RG were significantly higher than those in the HCG (). (c, d) Compared with before treatment, the expression levels of serum HOTAIR and TNF-α of patients in the two groups decreased significantly after treatment, and their expression in the RG was lower than that in the CG (). Note: Compared with the HCG, was less than 0.05. Compared with before treatment, ^a in the group was less than 0.05. Compared with the CG, ^b was less than 0.05.
