Index Medicus

I have to change my formatting from APA 6th to Index Medicus for the journal I am submitting to. Index Medicus is not one of the options in the selection of styles. Can anyone tell me if another style supported by Endnote is the same or close?

Thanks!

_Index Medicus _isn’t an output style, it is a way to abbreviate journal titles?  To learn about how to use Journal terms list to achieve this see this KB article and video.  http://endnote.com/kb/82228
