(a). Cortisol acute stress reactivity. Displayed as means of cortisol levels across the experimental session. PTSD symptom group – Baseline n = 19, After stressor n = 19, +8:00 n = 19, +13:00 n = 19; TC – Baseline n = 29, After stressor n = 29, +8:00 n = 29 + 13:00 n = 28, Error bars represent SDs. (b). Heart rate reactivity. Displayed as estimated marginal means of heart rates per minute during the task. PTSD symptom group n = 20, TC n = 27, Error bars represent SEs. (c). CAR and cortisol day curve. PTSD symptom group – CAR AUCg n = 13, AUCi n = 13, MaxInc n = 14, cortisol day curve AUCg n = 13; TC – CAR AUCg n = 21, AUCi n = 21, MaxInc n = 27, cortisol day curve AUCg n = 19. There were no effects of group on cortisol acute stress reactivity, heart rate reactivity, CAR or cortisol day curve. Error bars represent SDs
