: This study got the permission from the ethics committee. As the data were sourced from the Chinese Disease Prevention and Control Information System, researchers were subject to restrictions on access rights. Consequently, procedures for data retrieval, screening, and analysis were meticulously conducted to ensure the complete exclusion of patients’ identifiable information, including names, ID numbers, and residential addresses. Hence, the Ethics Committee of the Guizhou Center for Disease Control and Prevention deemed ethical approval and participant consent unnecessary for this study.
