  1. aData from 974 to 978 patients were available for analyses except 902 for CDAI, 949 for HAQ, 966 for Pain VAS, and 903 for PhGA.
  2. bThe slope coefficients (β) with their standard errors (SE), and p values corresponding to the three specified comparisons in the unadjusted analysis are presented. The cut-off between low and high positive ACarPA was 3× the upper limit of normal.
