It would be informative to consider test-specific duties as well as rank/occupation of Army and Marine personnel in building an appropriate comparison cohort, as the CROSSROADS study was able to do in significant numbers for Navy personnel.
- What can we learn by analyzing, in addition to the underlying causes used in this report, the associated causes of death listed on death certificates for the CROSSROADS participants and controls? Might there be clues to reporting bias? Might there be information that gives us a better understanding of the morbidity experience of these individuals? Finally, can the contribution of a self-selection bias in the participant cohort be quantified? And, how best can we control for it in ongoing and future studies of atomic veterans?
