Q. “These are results of two previous double-blind, repeat-dose studies of XYZ (studies 000 and 001).” Although the word studies before 000 and 001 is not capped, do you ever cap a preceding word before the study number, and if the preceding word is a plural, such as studies, should it be capped before the respective number/name? Thanks.

A. Chicago does not cap in such phrases, whether singular or plural. We do cap if the word is part of a proper-noun phrase: Mounts McKinley and Olympus.
