Figure 3.

Juvenile Idiopathic Arthritis–American College of Rheumatology (JIA‐ACR) 30, 50, 70, 90 improvement criteria response rates over time for patients ages 6‐17 years (cohort 1; intent‐to‐treat [ITT] population analysis) (A) and patients ages 2‐5 years (cohort 2; ITT population analysis to month 4 [study part 1], “as‐observed” population analysis thereafter to month 24 [study part 2]) (B). Bars show the 95% confidence intervals. The apparent decrease in response rates at month 24 in cohort 1 reflects a decreased number of patients with available data at this time point and the associated increased proportion of patients imputed as nonresponders due to missing values.
