Adami et al. conducted a retrospective analysis to evaluate the GC sparing effects of JAKi versus bDMARDs in rheumatoid arthritis patients. They found that JAKi therapy was associated with a significant reduction in GC dose compared with bDMARDs. This suggests that JAKi could be more effective in reducing long-term GC exposure in RA patients.
