  1. CI, confidence interval. Dropout analysis at baseline and at 3 months derived by comparing responders with dropouts at baseline and at 6 months respectively.
  2. 1Analysed with chi-square test based on data from the baseline questionnaire.
  3. 2Analysed with chi-square test based on data from three-month assessment.
  4. 3Including six responders who were non-responders at 3 month follow-up.
  5. 4Missing variables for ongoing PTSD was < 1%.
