Changes from baseline were calculated using data only from patients with data available at both baseline and month 12 or at both baseline and month 24
For DAS-II cluster and composite scores: mean = 100; standard scores of ≤ 69, 70–79, 80–89, and 90–109 indicate very low, low, below average, and average function, respectively
