Ethical Considerations

The TCGS evaluation proposal was reviewed according to KFL&A Public Health's policy for scientific and ethical review.

A letter of informed consent was signed by those participating in the evaluation of the TCGS (Appendix 4). All data were treated as confidential and were managed in compliance with KFL&A Public Health's record retention guidelines. A study key linking names to the data set was stored electronically. This key was deleted once the dataset was complete. The data file did not contain names, and results were reported in aggregate form without names or personal identifiers.
