Precoordinated expressions consist of a singleidentifier, followed optionally by any term that is associated with that. While the use of a term is not mandated, it is often preferable to includes from includefrom an appropriate dialect within the expressions to improve the human-readability of the expression. For example:
| Scg expression |
|---|
| Border | ridge |
|---|
| ShowFormat | block |
|---|
|
73211009|Diabetes mellitus| |
As mentioned, the syntax does not require a term to be used with each concept identifier, so the following is also a valid:
| Scg expression |
|---|
| ShowParts | id |
|---|
| Border | ridge |
|---|
| ShowFormat | block |
|---|
|
73211009|diabetes mellitus| |
