Authorship Correction: International Changes in COVID-19 Clinical Trajectories Across 315 Hospitals and 6 Countries: Retrospective Cohort Study (Preprint)

UNSTRUCTURED Authorship Correction: International Changes in COVID-19 Clinical Trajectories Across 315 Hospitals and 6 Countries: Retrospective Cohort Study 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. doi: 10.2196/31400), two errors were noted. Due to a system error, the equal contribution of the last three authors was not noted. To correct this under the JMIR parameters allowing only one equal contribution footnote, we are implementing the following changes. In the originally published paper, equal contribution was noted as: “Griffin M Weber MD, PhD1*, Harrison G Zhang1*, Sehi L'Yi PhD1*,… *These authors contributed equally” This has been corrected to: “Griffin M Weber MD, PhD1*, Harrison G Zhang1*, Sehi L'Yi PhD1*,… Tianxi Cai ScD1*‡, Andrew M South MD, MS36*, Gabriel A Brat MD, MPH1*… *These authors contributed equally” Additionally, the Authors’ Contribution section has been updated to include: “These authors contributed equally: Griffin M Weber MD, PhD, Harrison G Zhang, Sehi L’Yi PhD. These authors jointly supervised the work: Tianxi Cai ScD, Andrew M South MD, MS, Gabriel A Brat MD.” The correction will appear in the online version of the paper on the JMIR Publications website on November 2, 2021, together with the publication of this correction notice.
