Bold has been used to highlight results that were statistically significant at the level. Model covariates: baseline version of outcome, gender, and baseline PHQ-9 (for comorbidity of depression) (removed for analysis of PHQ-9 as an outcome else duplicated from before) and time since trauma (in months).
