| + | ===== Hierarchical crosswalks ===== | ||
| + | |||
| + | The PPI Hierarchical crosswalks include only standard concepts. A PPI standard concept value depends on the existence of an equivalent mapping either to the SNOMED or LOINC. In turn, a standard SNOMED/LOINC equivalent, if present, takes place of a non-standard PPI concept in the Internal PPI Hierarchy and adopts all its ancestors and descendants. | ||
