Change Type: Update

Change Details: The original version of this article was revised: a typographical error in several instances mixed the digits “3” and “8.” The corrected total number of patients with at least one of the diagnoses is 3433, not 3488. The title’s subheading, the abstract’s Results section, and the first paragraph of the Results section have been revised. Furthermore, the number of patients with a collagen synthesis disorder is 1808, not 1803 as written in Table 2. In Figure 1, the box with results for both diagnosis groups is duplicated, and the box for patients with only Perthes’ disease is missing; and the number of excluded cases is incorrect, because of later adjustments in the calculations. The box for exclusions should be 2 127 678 and not 2 127 623.
