Notes

  • Both source_vocabulary and target_vocabulary are required parameters
  • The unmapped_concepts array contains a sample of up to 100 unmapped concepts
  • Coverage percentages are calculated based on valid, non-deprecated concepts
  • Use domain_ids to focus analysis on specific medical domains
