These differences were also detected among CD4 positive T cells when comparing the EM and CM T helper subset in the JAKi group with healthy and RA controls [20.47 (14.77–30.69), 10.79 (7.16–16.25), and 12.12 (7.62–17.05); p < 0.0001 in both cases; and 38.40 (29.26–45.66), 48.87 (42.07–56.52), and 48.32 (43.82–58.8), p = 0.002 and p = 0.001, respectively]. The gene discussed is CD4; the disease is rheumatoid arthritis.
