  • *Tertiles originate from figures 1 and 2.

  • †p Value from the analysis of variance on the van der Waerden normal scores is to test for equivalence across tertiles. Median values across the tertiles are indicative of trends.

  • ADA, adalimumab; CRP, C-reactive protein; JE, joint erosion; JSN, joint space narrowing; MTX, methotrexate; TA-DAS28(CRP), time averaged 28-joint disease activity score with C-reactive protein; T1, tertile 1; T2, tertile 2; T3, tertile 3.
