Clarifications About Reporting of Studies of Bioengineered Arteries for Repair of Extremity Vascular Injuries

Corrections and clarifications have been made to the Original Investigation titled “Bioengineered Human Arteries for the Repair of Vascular Injuries,”¹ published online on November 24, 2024, and in the February 2025 issue of JAMA Surgery. These include indication that all main findings are limited to an analytic subset of 67 participants with extremity vascular injuries; more clearly indicate that 19 participants were excluded; define the 3 types of injuries; describe the relevant amendments to the protocols; add the specific numbers of the participants analyzed for the efficacy and safety outcomes to Table 2; add a new eTable 3 in Supplement 7 with adverse events of all participants enrolled in the studies, including those with iatrogenic and torso injuries; acknowledge that had the 19 excluded participants been included in all the analyses, the efficacy and safety findings could have been attenuated; and note the authors’ plan to report additional analyses of the excluded participants separately. The authors have explained these corrections and clarifications in a Letter,² and the article has been corrected.
