Corticotropin and cortisol response to the Trier Social Stress Task. Data are shown as mean ± standard error of the mean (SEM) of the base 10 logarithm transformed data. High and low trauma groups were determined using the median split of the total number of ETI occurring in the sample data. The median (range, IQR) number of total ETI occurring in the sample is 11 (range: 2–48, IQR: 5–18). Of the 39 total subjects, 20 are considered to have a high number of total ETI (median: 18, range: 11–48, IQR: 14–24) and 19 are considered to have a low number of total ETI (median: 5, range: 2–9, IQR: 4–7).
