OR: odds ratio; 95% CI: 95% confidence interval; NPP: nuclear power plant; FY: fiscal year; PCL-S: PTSD Checklist–Specific. In the adjusted model, mean VIF = 1.05 [range: 1.02–1.12] for delayed effect, mean VIF = 1.06 [range: 1.02–1.16] for genetic effect. The predictors were traumatic reactions, and all the other variables were simultaneously controlled for.
