I have a simple question.
When mapping two vocabularies, the mapping can vary depending on where you start.
It may be different between ‘from ICD10 to SNOMED’ and ‘from SNOMED to ICD10’.
In CONCEPT_RELATIONSHIP table,
45537706 198677 Maps to 2014-07-01 2099-12-31
45537706 is Cholera (A00) in ICD 10.
198677 is Cholera(63650001) in SNOMED.
So the above example means OHDSI maps from 45537706 to 198677.
OHDSI maps from ICD10 to SNOMED.
Is it right?
