The proportion of patients recalling traumatic memories in different groups (all patients, '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, indicating an increased risk for development of post-traumatic stress disorder, and 'low-scoring patients' with PTSS-10 score below the cutoff score). The χ2 test revealed a significant difference of frequency in anxiety memories between groups. n.s., non-significant difference. aSignificant difference; btrend.
