y year, SD standard deviation, IL-6 interleukin-6, IL-1β interleukin-1β, TNF-α tumor necrosis factor-α, CAPS Clinician-Administered Posttraumatic Stress Disorder Scale for DSM-4, NA not applicable.
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.
