Association between stressors and risk/mitigating factors and depression and anxiety, and how these changes across time, compared with pre-deployment as baseline^*.

AOR = adjusted odds ratio; CI = confidence interval. p values <0·05 were considered statistically significant and are in bold type. *Chronic stress and time are interacting, which means that the effects of chronic stress on depression are different among pre-deployment, post-deployment, and follow-up. †p value: predictor × time interactions. §Trauma exposures are defined as follows: Category 1 = 0 trauma events. Category 2 = 1–4 traumatic events. Category 3 = ≥5 traumatic events.
