Advance Online Publication of an Article or ePub Ahead of Print:

Sometimes you will come across an article that has been published online, ahead of the print version (PubMed refers to these articles as ePub ahead of print).  When citing an ePub ahead of print article your reference must indicate this status.  Keep in mind that the article may not have a volume number or page numbers.  When this is the case simply omit that part of the citation.  See the example below:
