C.1 Adapted a published search strategy.
Unclear
C.2 Asked experts for suggestions of relevant terms.
Unclear
C.3 Used a database thesaurus.
Unclear
C.4 Statistical analysis of terms in a gold standard set of records (see B above).
No
No gold standard was identified.
C.5 Extracted terms from the gold standard set of records (see B above).
No
No gold standard was identified.

Yes
Many terms to capture the concept of patients are combined (using AND) with concepts capturing emotions, experience and other issues.
