Fig. 3From: Clinical significance of long non-coding RNA NORAD in rheumatoid arthritisExpression of inflammatory factors and its correlation with serum NORAD. (A-B) ELISA assay revealed increased serum IL-6 and TNF-α levels in RA patients. (C-D) IL-6 (r = 0.6373, P < 0.0001) and TNF-α (r = 0.5643, P < 0.0001) levels were directly proportional to NORAD expression. ***P < 0.001Back to article page
