: All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee at which the studies were conducted (IRB approval number: the Takeda Hospital Group (Approval no. 1807), the University of Tokyo Graduate School of Medicine and Faculty of Medicine (Screening no. 2018063NI)), and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards. This was a retrospective study involving human data that were previously collected and did not require the additional recruitment of human subjects; thus, the need for informed consent was waived via the opt-out method on the hospital’s information.
