  • N=number of patients who met the criteria for the effectiveness cohort, that is, initiated etanercept after CARRA Registry enrolment, had a registry visit ±14 days from etanercept initiation had uninterrupted etanercept use, and had a 6-month or 12-month follow-up visit. Dosing calculation reflects the weight at visit closest to the time of etanercept initiation (within 9 months before 9 months post-initiation); no patients were excluded due to no weight available for dose calculation.

  • CARRA, Childhood Arthritis and Rheumatology Research Alliance; Q1, quartile 1; Q3, quartile 3.
