There was a longer duration of follow\u2010up and a wider range of body size in the CARRA Registry compared with the historical clinical trials. When matched on trial inclusion, the ACR\u2010Pedi response rates broadly aligned with those observed in the trials for adalimumab, whereas the sample size for canakinumab limited comparisons for the response rate.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Children encountered in clinical practice had wider ranges of body size and less severe disease at drug initiation. These results underscore that registration trials may be enriched for patients with more severe disease and are not fully representative of the broader JIA population who use these drugs after marketing. Real\u2010world evidence generated from observational data may play an increasingly important role in regulatory decision making, along with the continued need for controlled clinical
