Tight Control and Radiological Progression: The Radiographic Outcomes of the TICOPA Study

J Rheumatol 2025; doi:10.3899/jrheum.2024-1035In the Abstract, Results, regarding the definition of radiographic progression, the text should be "an increase in total erosion score of ≥ 2 at week 48." Similarly, in the Results section on page 3, paragraph 1, the text should be "On evaluation of radiographic progression (defined as an increase in total erosion score of ≥ 2) at week 48, 17/169 patients (10.1%) were found to have radiographic progression, representing 14.1% (12/85) of the StdC arm vs 6% (5/84) of the TC arm." The authors would like to clarify that radiographic progression is defined as an increase in the total erosion score of ≥ 2. We apologize for any lack of clarity. This clarification does not affect the conclusions of the study.This correction applies only to the February 15 2025 First Release. The correct text appears in the print and online issues.
