: The KWCS was approved by Statistics Korea and conducted in accordance with Article 18 of the Statistics Act (approval no: 380002) in South Korea. Data are available to the public with safeguards to protect participants’ anonymity and privacy rights. All participants provided informed consent for voluntary participation. Considering the use of completely de-identified open-source data and the participants’ privacy rights, this secondary data analysis did not require ethical approval from an internal review board. In Italy, ethical committee approval was not required for retrospective anonymized studies, such as KWCS repositories.
