Mean salivary cortisol awakening responsea in female and male participants according to posttraumatic stress disorder status

Sex: PTSDb
Mean µg/dL (95% CIc) 		No PTSD
Mean µg/dL (95% CI) 		P-valued
Female 0.03 (−0.03, 0.09) 0.07 (−0.01, 0.14) 0.43
Male 0.01 (−0.11, 0.12) −0.02 (−0.12, 0.08) 0.79
a

Difference in cortisol level between salivary collection time 1 (awakening) and 2 (awakening + 30min), with 2 observations per person (collection day 1 and collection day 2)

b

PTSD = posttraumatic stress disorder

c

CI = confidence interval

d

P-value from regression model of ln(cortisol difference) and PTSD adjusting for age, collection day, and alcohol consumption in the past month.
