Table 2.
Statistics for simple regressions run on the 8 ROIs depicted in Fig. 5. Rows 1 and 2: ROIs extracted from the CAPS vs. thickness analysis in the full sample (n = 104). First two columns show regression analysis statistics from the whole sample (n = 104) and second two columns show statistics from lifetime subgroup (n = 85). Rows 3 and 4: ROIs extracted from CAPS vs. thickness in all subjects with current PTSD (n = 65). First two columns show statistics from all subjects with current PTSD (n = 65) and second two columns show statistics from individuals in the lifetime subgroup who also have current PTSD (n = 55). Rows 5 and 6: ROIs from CLB-P vs. thickness in lifetime subgroup (n = 85). Rows 6 and 7: ROIs from CLB-P vs. thickness in subjects with current PTSD (n = 55). Reported F values are Fischer's statistics and R2 values are coefficients of determination.

Correlation values were significantly different between CAPS and CLB-P as tested by Steiger's Z-test at p < 0.05.
