Within the first year post-transplant, 45/67 (67%) patients who received induction with ATG were at least once hospitalized due to an infection, compared to 46/67 (69%) patients who received induction with IL-2 RA (Hazard Ratio [HR]=0.9292; P=0.6705; Figure 3A). This evidence concerns the gene IL2 and rheumatoid arthritis.
