Acute MDD symptom severity was associated with persistent PTSD (OR: 1.17; 95% CI: 1.08, 1.27) and remained significant after inclusion of acute PTSD symptom severity (OR: 1.14; 95% CI: 1.01, 1.29). In an analysis of PTSD symptom clusters, reexperiencing symptoms (OR: 1.18; 95% CI: 1.02, 1.36) and MDD symptom severity were associated with persistent PTSD. In models of persistent MDD, acute PTSD symptom severity was associated with persistence (OR: 1.15; 95% CI: 1.03, 1.28), but neither overall symptom severity nor cluster symptom severities were
