We estimated the rG of PTSD phenotypes [i.e. PTSD (PGC), and PTSD Re-Exp (MVP)] with DPW (from the GSCAN, UKB and both combined), AUDIT-C (from the MVP and UKB), and AUDIT-T (from 23andMe and UKB) (see Table 2 and Fig. 1). We also estimated rG with Max. Alc. (from the MVP), AUDIT-P (from the UKB), AUD (from the MVP) and AD (from the PGC) in individuals from EA. Similarly, we estimated the rG of PTSD and PTSD Re-Exp with AUDIT-C (from the MVP), Max Alc (from the MVP), AUD (from the MVP), AD (from the PGC) phenotypes in AA samples (see Table 3 and Fig. 2).
