As shown in Figure 2, serum Gal-9 levels were positively correlated with sTIM-3 levels (p < 0.01), FABP1 levels (p < 0.01), FABP4 levels (p < 0.01), DAS28-ESR score (p < 0.001) and US-FLI score (p < 0.01), respectively, in RA patients. This evidence concerns the gene FABP4 and rheumatoid arthritis.
