Systolic blood pressure (SBP) reactivity as a moderator of the relationship between Task Strain and carotid artery Intima-Medial Thickness (IMT). N= 460 with complete data. Regression models were fitted using log-transformed IMT scores to reduce skewness, but the figures present inverse-transformed scores and their standard errors (calculated via Taylor approximation) to enhance interpretability. Figures present the data where reactivity measures are centered 1 sd above (low reactors) and below (high reactors) the mean. Covariates in this model included age, sex, race, education, current smoking status, clinic systolic blood pressure, fasting plasma glucose, LDL and HDL cholesterol, fasting insulin, and waist circumference.
