Note. Data are shown as mean ± SE and R ² derived from robust regression. Mu‐RT is a measure of central tendency; sigma‐RT is a measure of variation of the normal distribution; tau‐RT is a measure of the mean of exponential component of distribution. Stress reactivity is a difference score between stress task and baseline values; stress recoveries are the difference scores between each poststress recovery value and baseline. Regression coefficients are adjusted for the baseline (prestress) value of the cardiovascular outcome, age, sex, BMI, employment grade, correct Stroop trials (cognitive ability), and self‐report stress task difficulty and involvement rating. SBP = systolic blood pressure; DBP = diastolic blood pressure; HR = heart rate; HRV = heart rate variability.
