The article, “Clinical Correlates and Heritability of Flow-Mediated Dilation in the Community: The Framingham Heart Study,” by Benjamin et al, which appeared in the February 10, 2004, issue of the journal (Circulation. 2004;109:613–619), the authors regret that they incorrectly described the method of blood pressure ascertainment. In the regression models, instead of using the automatic blood pressure device (Dinamap, Critikon, Inc), they actually used the average of the physician’s first and second blood pressures from the same morning as the brachial testing. The regression models using the Dinamap blood pressure produced very similar results. Hence, for Table 1, the correct mean systolic and diastolic blood pressures were 128±17/76±10 for men and 126±20/73±10 for women. (The reported values were were 128±17/75±10 for men and 122±18/67±11 for women.) The corrected rows of Table 1 appear below.
