Results from regression analyses investigating relationship between deployment experiences and gray matter volume.

Note: Gray matter volume determined using FSL implementation of voxel-based morphometry. Average t statistics and unstandardized regression coefficients were extracted for significant clusters of activation. Deployment experiences included scores on the combat experiences and deployment social support subscales of the Deployment Risk and Resilience Inventory. Analyses were partial regressions investigating main and interaction effects of each predictor with N = 32 combat veterans from Operation Iraqi Freedom or Operation Enduring Freedom (OIF/OEF).
