Since this community may be knowledgeable about non OMOP stuff (and there is no better venue I could ask) - I am hoping to ask a simple question about PCORNet CDM.
In PCORNet CDM, two tables have a suffix “_CM” (they are LAB_RESULT_CM and PRO_CM).
I did not see in the spec what it stands for and why just these two tables would have that suffix.
Does anyone know the meaning of the _CM suffix in the table name?
