aMean concentration for serum samples with detectable ligand levels.

bIn the subset of serum samples available, one sample from a healthy donor and one from a patient with SLE were not assayed because of insufficient volume.

LOQ, limit of quantitation; RA, rheumatoid arthritis; SD, standard deviation; SLE, systemic lupus erythematosus.
