2. Within 90 days prior to DTAS deployment date.
We stratified our sample into groups by time post-deployment which was computed as the difference between the veterans' clinical evaluation date and return from deployment date.
Since we do not have pre- or early post-deployment data on this clinical sample it is impossible to say if the service members have worsened over time, if their condition has always been poor, or if those who were seen further from their deployment date simply had a higher threshold for seeking care in the face of symptoms.
Note: Significant difference by gender (P < 0.001), prior deployment (P < 0.001), and military occupation (P = 0.006) by Chi-square. 1. Demographic characteristics as of the deployment date.
We abstracted from the veterans' clinical evaluation records the following information: demographics, deployment dates, probable diagnosis of PTSD and responses on the Veterans version of the Short Form 36 Health Survey (known as the Veterans RAND or VR-36).

For these analyses, electronic records from DMDC provided information on age, sex, race/ethnicity, education, pay grade, service branch, service component, military occupation, dates of separation, and deployment dates.
