load also increased risk for ND even after PTSD was included (OR= 1.14, 95% CI=1.06–1.24; based on regression coefficient τ′ in Table 4), suggesting that TE plays a role in ND that is independent of PTSD. Results for ND were consistent when controlling for AD and MD in that TE and PTSD were related to ND; the TE effect was reduced when PTSD was included, but TE effect was still significant.
