Description of the illustration ppath

This figure shows the difference between sample derivation paths in MedDRA in which one uses primary links, the other primary paths. In the primary links example, the two PT-level terms have a primary link to the HLT level, and must derive the same SOC-level term. Using primary paths, you can enable PT-level terms to link to the same HLT-level term, but derive different SOC-level terms.
