Difference in mental and physical component summary between groups. The mental and physical component summary of health-related quality of life was measured with the Medical Outcomes Study 36-Item Short Form (SF-36), comparing between 'high-scoring patients' with a Post-Traumatic Stress Syndrome 10-Questions Inventory (PTSS-10) score greater than or equal to the cutoff score of 35 points, indicating an increased risk for development of post-traumatic stress disorder, and 'low-scoring patients' with a PTSS-10 below the cutoff score, and age- and gender-matched healthy controls. Significant difference (***p < 0.0001)was calculated with analysis of variance and post-hoc t tests for independent samples. The broken line indicates a significant difference between groups as determined with the t test.
