In addition, considering the whole cohort of RA in stable clinical and US remission, BMI value directly correlated with the IHC scores for sublining CD68+ (R = 0.39; p = 0.001) whereas no correlations were found between BMI and sublining CD3+ (R = 0.30; p = 0.14) and CD20+ cells (R = 0.10; p = 0.63) (Fig. 4L). Here, CD68 is linked to rheumatoid arthritis.
