*The Wald test p<0.25 for variables: occupation categorisation, sex, rank, years of service and live-in dependents (MI).
†Facility support included occupations such as construction engineers, fire fighters, plumber/gas fitter and technicians in—water, fuels and the environment, electrical distribution, plumbing and heating, refrigeration and mechanical systems, and weather systems processing.
‡Operations support included occupations such as logistics support, air traffic controllers, supply technicians, traffic technicians, postal clerks, administrative clerks, financial clerks, resource management support clerks and mobile support equipment operators.
¶Age and years of service were time-dependent variables, sample number, weighted %, and mean delay to care with the associated 95% CI are reported here at the deployment return date. The reported unadjusted HR and 95% CI incorporate the variables' time dependency.
**Multiple imputation was used to compute the unadjusted HR for variables: marital status (MI) and live-in dependents (MI).
