The original version of this Article contained an error in the Methods section, regarding ethical approvals. The data of three patients included from Hino hospital were not covered by the original ethical approval, which read: “This study was approved by the institutional review board, and the requirement of written informed consent was waived because of the study’s retrospective design (Keio University School of Medicine Ethics Committee approval number 2020-0033).” These patients provided their consent separately and an additional ethical approval was issued by the IRB of Hino Municipal Hospital. Additional information on the approval for study execution by the other participating centres was also included in the corrected version. The approval statement now reads.
