ADaM-to-SDTM Traceability Mapping — trace

Maps ADaM (Analysis Data Model) variables to their SDTM (Study Data Tabulation Model) source variables with derivation text and confidence scores. Includes direct copies, derived variables, and unmapped entries. Follows CDISC (Clinical Data Interchange Standards Consortium) traceability conventions.

Usage

trace_mapping

Format

A tibble with 25 rows and 6 columns:

adam_dataset: Character. Source ADaM dataset.
adam_var: Character. Source ADaM variable.
sdtm_domain: Character. Target SDTM domain (NA if derived).
sdtm_var: Character. Target SDTM variable (NA if derived).
derivation_text: Character. Derivation description text.
confidence: Numeric. Mapping confidence score (0-1, NA if unmapped).
