  1. Numbers represent result of Pearson correlation analysis between % change in carotid artery diameter between baseline and peak mental stress to the listed variables. Numbers in bracket represent the P values. Abbreviations: b, baseline; p, peak stress; SBP, systolic blood pressure; DBP, diastolic blood pressure; PSV, peak systolic velocity; EDV, end-diastolic velocity; TAM, time average mean velocity; IMT, intima media thickness.
