Two PTSD-related variables were used: DSM-based PTSD and a PTSD re-experiencing score. PTSD re-experiencing symptoms (PTSD Re-Exp) came from an assessment of the PTSD Checklist (PCL) DSM-IV (American Psychiatric Association, 1994) version (Wilkins, Lang, & Norman, 2011) in the MVP (Gelernter et al., 2019b), selected as it is the symptom cluster most distinctive for PTSD compared to other disorders. This sample and phenotype contributed to both EA (N = 146 660) and AA (N = 19 983) analyses.
