4 Publication of innovative original articles. WJMA's acceptance of a manuscript for publication is based on its novelty, innovativeness, data accuracy, image reliability, clear language expression, and ethical requirements. 

5 Disclosure of documents related to the article. The peer review report, author response to the peer review report, biostatistics review certificate, copyright license agreement, institutional ethics committee approval document, informed consent document(s), conflict-of-interest statement, CrossCheck detection report, corresponding author(s) personal ORCID number(s), funding information, language editing certificate, and other relevant documents will be published online along with the article to allow for an open and transparent publishing process.
