In Table E-1, we present the individual paygrade-level distribution by cohort. In the absence of military occupation information, the analysis attempted to explore whether the type of unit to which the participant and referent cohort individuals were assigned could be developed as an exposure proxy.

For leukemia only, for which our study results were most interesting, we did a formal analysis of the heterogeneity of risks among test series. We fit a baseline model including a variable that represented the number of the five series in which an individual participated: 0 (for refer

Notwithstanding this lack of a statistically significant difference in leukemia risk among the five series, we decided to undertake further investigations to identify subgroups with high leukemia risk. Part of the reason for this decision was to investigate further the significant excess risk among land series participants (see below)

In an attempt to get sharper estimates of leukemia and cancer mortality risk across series, we took the additional step of confining the analysis to individuals who participated only in their assigned series and at no other series. Limiting the analysis to participants who were at only one of the five series has the advantage of permitting an unconfounded comparison of mortality risks across test series, although the number of participants is reduced by roughly 15 percent, from 68,208 to 57,532.
