ANA Antinuclear Antibody, CRP C-Reactive Protein, ESR Erythrocyte Sedimentation Rate, n/a not available, NSAID Non-Steroidal Anti-Inflammatory Drugs, RF Rheumatoid Factor. Disease duration was calculated as the date of confirmed diagnosis of arthritis to date of enrollment in the study. CRP values were based on a blood sample taken at the clinic visit closest to study participation (^a CRP was measured from a study visit blood sample since participants did not have any recent clinic visits). Active Joints refer to joints assessed as tender or swollen by the participant’s rheumatologist at the clinic visit closest to study participation. Medications refer to those taken regularly by the participant at the time of study completion (Off medication duration: II = 5.0 years, and III = 0.9 years)
