Abstract

In Table 1, the units for the last row were labelled incorrectly. The value in the parentheses represents the number of individuals affected by serious infections, as some individuals had > 1 event of a serious infection. The revised variable is "No. of serious infections (n individuals)." We apologize for this error. This correction applies to the August 1 2025 First Release and print issue. The online version has been corrected. J Rheumatol 2025; doi: 10.3899/jrheum.2025-0029.
