Incorrectly Categorized Group Author

In the Original Investigation titled “Fractures and Linear Growth in a Nationwide Cohort of Boys With Duchenne Muscular Dystrophy With and Without Glucocorticoid Treatment: Results From the UK NorthStar Database,”¹ published online March 11, 2019, the UK NorthStar Clinical Network was incorrectly categorized as a contributor instead of as a collaborator and the group author members mistakenly included in the Supplement. The UK NorthStar Clinical Network was added to the byline, a Group Information section was added to the end of the article, and the eAppendix of the Supplement was removed. This article was corrected online.
