a decreasing trendP = 0.064
We found that the core enrichment genes ( n = 23) showed a decreasing trend between baseline and 6-month time points in improvers treated with abatacept ( Figure 2A , P = 0.064), with no significant changes in abatacept-treated nonimprovers ( Figure 2B ), placebo-treated improvers ( Figure 2C ), or placebo-treated nonimprovers ( Figure 2D ).
