Note. N = 24; CAPS = clinician‐administered PTSD severity scale; O‐PASS = orthostatic‐PA severity scale; O‐FSS = orthostatic‐PA flashback severity scale; O‐CCSS = orthostatic‐PA catastrophic cognitions scale. Systolic BP Δ change score = the SBP change score, which was calculated by subtracting the post‐orthostasis SBP nadir from the sitting value; diastolic BP Δ score = the DBP change score, utilizing the DBP value at the SBP nadir; HR Δ score = the HR change score, utilizing the HR value at the SBP nadir.

*P < 01, in respect to the difference between the two groups at that time point.
