Abstract

In “International Changes in COVID-19 Clinical Trajectories Across 315 Hospitals and 6 Countries: Retrospective Cohort Study” (J Med Internet Res 2021 Oct 11;23(10):e31400), two errors were noted. In the originally published paper, equal contribution of the last three authors was not noted. This has been corrected to add a note of equal contribution to the last three authors, as well as to add a statement to the Authors' Contributions section denoting the nature of equal contributions. In the originally published paper, an equal contribution footnote was applied to authors Griffin M Weber, Harrison G Zhang, and Sehi L'Yi. In the corrected paper, the equal contribution footnote has been applied to authors Griffin M Weber, Harrison G Zhang, Sehi L'Yi, Tianxi Cai, Andrew M South, and Gabriel A Brat. The Authors’ Contribution section has been updated to include the following statement: These authors contributed equally: GMW, HGZ, SL. These authors jointly supervised the work: TC, AMS, GAB. The correction will appear in the online version of the paper on the JMIR Publications website on November 30, 2021, together with the publication of this correction notice.
