Outcome - trial result metrics

Our ideal data model doesn't have a Outcome entity or field but the Cochrane database has. This entity/field stands for describing trial result metrics. For example: Negative Symptom Rating Scale (NSRS)

Proposed solutions

• we can have an entity Outcome with m2m relation with Trial (as in the Cochrane database)
• we can have a field Trial.outcome implemented as array of strings

Could tblOutcome yield ResultsItem in the ideal model? But there's no associated values for e.g. Negative Symptom Rating Scale (NSRS).

Here's an example of another dataset that should be conforming to the ideal model. Trial results are indeed reported in terms of outcomes:
