  • N = 364; however, some data were missing for nondemographic variables. Data are displayed as means (SD) or n (%) as appropriate. All variables except race revealed significant differences (P < .01) across BP categories for both the Fourth Report and the CPG.

  • a Stage 1 and stage 2 hypertension categories combined.

  • b cIMT recorded as a composite score (see text).
