3. Submit a request for correction or withdrawal: After contacting the journal editor, the author needs to submit a formal request for correction or withdrawal. The request should explain the nature and location of the errors and how to correct them. If the error is serious enough to affect the research results or conclusions, the author may need to withdraw the whole article.
4. Waiting for the reply of the journal: After the author submits the request for correction or withdrawal, he needs to wait for the reply of the journal. The journal editor will evaluate the request and decide whether to accept the correction or withdraw the request.
5. Issue a statement of correction or withdrawal: If a periodical accepts a request for correction or withdrawal, the author needs to issue a statement of correction or withdrawal in the periodical. The statement should explain the nature and location of errors and how to correct them.
6. Apologize to the readers: Finally, the author needs to apologize to the readers. Although the mistake was discovered after the article was published, the author still has the responsibility to ensure the accuracy of the article. By publicly apologizing, authors can show their commitment to scientific integrity and restore readers' trust.
Generally speaking, when mistakes are found in SCI articles after publication, the author should take immediate actions to ensure that the mistakes are corrected in time and safeguard his academic reputation and the reputation of the journal.
