Declarations

:

: This study was approved by the institutional review board (IRB) of Aichi Medical University Hospital (No. 2021–176). This study including human participants was also conducted in accordance with the tenets of the Declaration of Helsinki and its later amendments.

: The IRB granted a waiver of informed consent for this study based on the ethical guidelines for medical and health research involving human subjects established by the Japanese Ministry of Education, Culture, Sports, Science, and Technology; and by the Ministry of Health, Labour, and Welfare. The waiver was granted because the study was not an interventional study. Nevertheless, at the request of the IRB, we published an outline of the study on the Aichi Medical University website to give patients the opportunity to refuse to participate in the study, although none did. Personal identifiers were removed from the records prior to data analysis.
