These correlations (Pearson) support our main findings, regarding the increased RORC expression (Figure 2A; p < 0.01 and p = 0.054, respectively) of naive T cells in RA and PsA (no correlation Figure 1D), while the TBX21 expression of the naive cells of all patients and controls is similar (Figure 2B; strong correlation Figure 1E). Here, TBX21 is linked to rheumatoid arthritis.
