TTVL was lowest at the time of transplantation with a median (IQR) of 6.95×102 c/mL (2.48×102–2.35×103 c/mL) and 9.33×102 c/mL (2.18×102–4.97×103 c/mL) in the ATG and IL-2 RA group, respectively, with no significant difference between both groups at baseline. This evidence concerns the gene IL2 and rheumatoid arthritis.
