  2. aPerceived stress level was assessed using a visual analog scale to rate the stress level of the stress-exposed participants of data set 2 (n = 52) with respect to their worst traumatic experience throughout their career. Posttraumatic stress symptom severity was also measured in the stress-exposed participants of data set 2 using the CAPS (n = 52). Source data are provided as a Source Data file.
