"Among refugees it is estimated that approximately 3% to 86% of the population suffers from PTSD, depending upon the type of sample, the type of traumatic events, and the refugee groups that were studied [5]. In 2001, The Danish Ministry of Health estimated that at least 50,000 refugees in Denmark suffered from PTSD and/or depression and that 5 to 44% of them are estimated to have a history of torture [6]."
