Procedures
Harmonized data is generated by a central harmonization team (with the collaboration of studies).
Participant Inclusion
All CanPath participants from cohorts collecting data on the collection and processing of biological samples at baseline are eligible.
Infrastructure
Harmonized data can be transferred to external servers, and pooled data analysis can be achieved.

Information Content

The Baseline Biological Sample - Collection and Processing Harmonization Protocol includes information about variables collected at baseline by four of the six CanPath population-based cohorts: BC Generations Project, Alberta's Tomorrow Project, Ontario Health Study and CARTaGENE (Quebec). The current dataset is the second release and includes more than 2,790,000 biological samples donated at baseline. The harmonized dataset covers information on: * Biological Sample Collection * Biological Sample Shipping * Biological Sample Processing * Biological Sample Long-Term Storage * Standard PREanalytical Code (SPREC) v3.0

Initiatives Included

Harmonization

Complete - study-specific variable is the same as DataSchema variable (status detail = identical) or needs transformation to generate DataSchema variable (status detail = compatible)
Partial - categorical study-specific variable (status detail = proximate) or other types (status detail = tentative) could generate DataSchema variable but with loss of information
Impossible - study does not collect DataSchema variable (status detail = unavailable) or cannot be used to generate DataSchema variable (status detail = incompatible)
Undetermined - harmonization status not determined
Not Applicable - harmonization status is not relevant
