a clustering of cardiovascular risk factors:
Value

Viewed from 'round about', this clause is the receptive agnate of the clause:

Assigner/Agent.
If ASSIGNMENT is only an option for relational clauses of the intensive kind (Halliday & Matthiessen 2004: 237), then the process is
intensive, not circumstantial.
Viewed 'from above', association is a type of extension in figures of being-&-having (Halliday & Matthiessen 1999: 145-6), so this is an instance of
extension (meaning) being realised as elaboration (wording). (The meaning of extension is here lexicalised rather than grammaticalised.)
