All-cause total healthcare costs (excluding biologics) during 1, 2, and 3 years of follow-up (n = 542 per cohort). Costs are derived from a matched sample of patients with ≥3 years of continuous health plan enrollment from the index date (n = 542 per cohort). p values are derived from t tests comparing mean costs across cohorts within each year. Medical costs include all costs related to inpatient and outpatient visits, such as office visits and laboratory testing. Pharmacy costs include all costs related to outpatient pharmacy fills, with the exception of fills for biologic drugs (defined as abatacept, adalimumab, anakinra, certolizumab pegol, etanercept, golimumab, infliximab, rituximab, tocilizumab, and tofacitinib citrate)
