Note. Analysis includes 34 participants who underwent stress using EEfRT data collected 120 min post-TSST. Low probability = 12%; medium probability = 50%; high probability = 88%. △IL-6 refers to change in IL-6 from study entry to 120 min post-TSST. Ethnicity (0 = Non-Hispanic White; 1 = Asian/Latina/Black/Other).

Abbreviations. BMI = body mass index; CI = Confidence intervals; IL-6 = Interleukin-6; SE = standard error.
