I am formatting a manuscript for Obstetrics & Gynecology, which uses a citation style similar to JAMA but with references identified with numbers in parentheses. Current JAMA citation style uses superscript reference style.

I'd like to edit a citation style on my own but have no idea how to do it. I managed to get the code into the Zotero Style Editor, but I don't know how to change a style from superscript to standard script in parentheses.

Can anyone help me? The JAMA code I am trying to modify to O&G style is below.

Thanks,
Jennifer
