A novel method, system, and apparatus-the RDH Method-for evaluating antihypertensive treatment efficacy across patient populations is disclosed. In accordance to one embodiment, the RDH is a population vector index and graphical method that provides the means for the statistical assessment of antihypertensive treatment reduction, duration, and homogeneity using ambulatory blood pressure monitoring (ABPM). The population RDH was specifically designed as a tool to evaluate and compare blood pressure (BP) coverage offered by antihypertensive drugs over 24 h in populations. In accordance to one embodiment, the population RDH is a three-component vector index that incorporates information about the reduction, duration, and homogeneity of antihypertensive treatment, as well as their statistical significance over the 24 h period. In the preferred embodiment, the population RDH components quantify: 1) the total number of statistical significant BP reductions, 2) the maximum number of consecutive statistical significant reductions, and 3) the maximum number of consecutive non-significant reductions over the 24 hours, respectively; and reports two population graphs that characterize the effect of the treatment. The output of the RDH index can be used in clinical trials to characterize the effects of antihypertensive medications, and in clinical practice to guide antihypertensive treatment.
