comments

Relevant exposures remain uncertain even after checking
Check exposures: at least one exposure group code needs to be checked during re-evaluation step
Check job code: ISCO code needs to be checked during re-evaluation step
Detailed instructions for coding or exposure assignment changes to make during the re-evaluation step
