^aAll variables that were significant in separate multivariable models that adjusted for socio-demographics (gender, current age, race, education, and marital status) and service-related characteristics (age at entry into Army service, time in service, deployment status, delayed promotion, demotion, military occupation) were examined together in a final multivariable model

^bOR = Odds ratio; CI = Confidence interval

^c< High School includes: General Educational Development credential (GED), home study diploma, occupational program certificate, correspondence school diploma, high school certificate of attendance, adult education diploma, and other non-traditional high school credentials

^dSoldiers above the rank of E4 are not promoted on a set schedule

^eCombat Arms includes Combat Arms and Special Forces soldiers

^fAmong soldiers who were diagnosed with a disorder classified as “Other,” 33/37 (89.2%) were identified by the ICD-9-CM code 300.9 (Unspecified nonpsychotic mental disorder)
