In a previously described RA cohort [6], plasma galectin-3 was significantly (n = 47, P <0.05 for all) and positively correlated with plasma IL-6 (r = 0.29), prednisone use (r = 0.42), BMI (r = 0.32), thigh cross-sectional area (r = 0.46), intra-muscular fat (thigh muscle density, r = −0.44), and age (r = 0.39). This evidence concerns the gene LGALS3 and rheumatoid arthritis.
