  1. Gene symbol with preceding “c” indicates antibody to citrullinated recombinant antigen. Sensitivity (Sens) at 90% specificity (Spec), otherwise at optimal area under the curve according to ROC analysis. Odds ratio (OR) for diagnosis of RA by generalized linear modeling with unadjusted p value (p), or after adjustment according to Bonferroni
