When a pathogen was detected, it was more commonly viral (N=86 in total; 47 in the ATG and 39 in the IL-2 RA group) or bacterial (N=91 in total; 52 in the ATG and 39 in the IL-2 RA group), with some instances of fungal infections (N=10 in total; 4 in the ATG and 6 in the IL-2 RA group; Figure 5B). Here, IL2 is linked to rheumatoid arthritis.
