Comparison of Abatacept Efficacy by Age Group Assessment of abatacept efficacy in younger and older patients showed that a numerically smaller proportion of patients in the AO group had a EULAR good response at week 24 compared with the AY group, although this difference did not reach statistical significance (31.3 vs. 48.9%, OR: 0.476, 95% CI 0.220–1.029, p = 0.0884) (Fig. 4 a).
