(A) Disease activity by DAS28 in patients treated first with infliximab, then with etanercept. Values shown are the mean value at baseline (before infliximab treatment), mean best value during infliximab treatment, mean value at last visit while on infliximab (when decision to switch was made), mean value just before starting etanercept treatment, and mean best value on etanercept. Comparisons are by paired two tailed Student's t test. (B) Swollen joint count in patients treated first with infliximab, then with etanercept. Values shown are the means at baseline and after three months for each treatment. Comparisons are by paired two tailed Student's t test.
