Sometimes more information will come to light after an article has been published. There may be an update, a correction, or even a retraction or withdrawal.
This is an important part of the scientific process, and it’s important to make it clear that this has happened - both on the article page itself, and in the metadata about the article. Your journal will be more trustworthy if you are transparent about when this has happened.
