Figure 2. Mean cortisol concentrations (in nanomole per liter; A) and systolic/diastolic blood pressure levels (in millimeters of mercury; B) over the course of the testing session. SECPT: Socially Evaluated Cold Pressor Test; SBP: Systolic blood pressure; DBP: Diastolic Blood Pressure. Error bars represent standard errors of the mean. ***pBonf < 0.001 compared to non-stressed participants. Times are relative to termination of SECPT/Warm water control. Note: due to issues regarding calibration of the assay, cortisol values turned out unusually high.
