Greetings, again!
A lightning flash took over the above post before I could finish it!
To continue: Purdue also has an APA citation site. I can't post the link here, but you can do a search for "MLA citations", and it should come up.
You are correct to cite your factual information, whether it's a quotation or not. You can legitimately cite the AMA journal if you can access it through your university library library database (which you probably can). The librarians would be able to help you.
The best way to learn citation styles, assuming you don't want to purchase the manuals, is to search out relevant web pages online. As I mentioned, the Purdue site (which they call OWL) is excellent.
Good luck, and thanks!
