Table 2.

Number of mappings from different preclinical and clinical terminologies to SNOMED CT. The number of used concepts for HPATH and MA is based on eTOXsys, SEND code lists on the SEND database, and MedDRA on the clinical databases. The last column shows the percentage of records from these data sources with concepts that have been mapped
