NOTES: n = number in subsample. The none group contains individuals with no history of CAN, PTSD, or an arrest for violence. The letters (a, b, c) reflect differences or lack of differences in pairwise comparisons. When two groups have different letters, they are significantly different from one another on that characteristic at p < .05.
