The _C_FULLNAME_ is the hierarchical path that leads to the term. Below is an example of the _C_FULLNAME_ for the term "Rheumatoid arthritis". It is shown on several lines but is actually one concatenated line in the _C_FULLNAME_ column. Each back slash () represents another hierarchical level.
\Musculoskeletal and connective tissue (710-739)
\(714) Rheumatoid arthritis and other arthropathies
\(714-0) Rheumatoid arthritis\
Each element of the path is separated by a backslash. Every element of the path must include a backslash, and there must be a trailing backslash at the end.
