Accepted and E-pub version articles are published online before they appear in a regular issue of the journal. Accepted articles are PDF versions of manuscripts that have been peer reviewed and accepted for publication, but not yet copyedited or typeset, allowing readers the most rapid access to accepted papers. The accepted article remains on this page until the final proof version of the paper is posted in Epub Ahead-of Print page.
Accepted article is given its own Doi, so it can be citable as it has been linked to PubMed.
