Two years after assessment, the low to normal SBP group tended to have the highest cumulative all-cause mortality (11.5%), compared with mortality rates of 8.5% and 7.5% in the normal and high SBP groups, respectively. Similar patterns were seen with vascular mortality. After adjusting for covariates, compared with the high SBP group, the low to normal group had higher all-cause mortality (adjusted hazard ratio, 1.96; 95% confidence interval, 1.13\u20133.39;\n                      <jats:italic>P<\/jats:italic>\n                      =0.017) and trended toward higher vascular mortality (adjusted hazard ratio, 2.08; 95% confidence interval, 0.93\u20134.68;\n                      <jats:italic>P<\/jats:italic>\n                      =0.075).
