JAMA Network | JAMA Psychiatry | Risk of Suicide Among US Military Service Members Following Operation Enduring Freedom or Operation Iraqi Freedom Deployment and Separation From the US Military: Design, Setting, and Participants� This retrospective cohort design used administrative data to identify dates of deployment for all service members (October 7, 2001, to December 31, 2007) and suicide data (October 7, 2001, to December 31, 2009) to estimate rates of suicide-specific mortality. Hazard ratios were estimated from time-dependent Cox proportional hazards regression models to compare deployed service members with those who did not deploy.

Main Outcomes and Measures� Suicide mortality from the Department of Defense Medical Mortality Registry and the National Death Index.
