I have read through the GRADE handbook and the publications on the GRADE guidelines (e.g. 1-3, 11, 13).

Unfortunately, I can't find any answers to my question:

How do I assess outcome domains (e.g. psychiatric symptoms, social functioning, personality functioning, etc.) if multiple outcomes are assessed for one domain in a single study (e.g. domain "psychiatric symptoms": depression symptoms and of eating disorder symptoms)?

I appreciate your help.

Kind regards
