In 2 patients (3%) there were no data for PTSD. PTSD, post-traumatic stress disorder; SD, standard deviation of the mean; 'high-scoring patients', 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 of development of PTSD; 'low-scoring patients', patients with a PTSS-10 score below the cutoff score; APACHE, Acute Physiology and Chronic Health Evaluation; ICU, intensive care unit; ARDS, acute respiratory distress syndrome; ECMO, extracorporeal membrane oxygenation. Significance was assumed at a two-tailed p < 0.05. aSignificant difference; btrend. |
