          Abstract

          Hibiscus sabdariffa L. is a tropical wild plant rich in organic acids, polyphenols, anthocyanins, polysaccharides, and volatile constituents that are beneficial for the cardiovascular system. Hibiscus sabdariffa beverages are commonly consumed to treat arterial hypertension, yet the evidence from randomized controlled trials (RCTs) has not been fully conclusive. Therefore, we aimed to assess the potential antihypertensive effects of H. sabdariffa through systematic review of literature and meta-analysis of available RCTs.

            Meta-analysis and subgroups.

            Subgroup analysis is the process of comparing a treatment effect for two or more variants of an intervention-to ask, for example, if an intervention's impact is affected by the setting (school versus community), by the delivery agent (outside facilitator versus regular classroom teacher), by the quality of delivery, or if the long-term effect differs from the short-term effect. While large-scale studies often employ subgroup analyses, these analyses cannot generally be performed for small-scale studies, since these typically include a homogeneous population and only one variant of the intervention. This limitation can be bypassed by using meta-analysis. Meta-analysis allows the researcher to compare the treatment effect in different subgroups, even if these subgroups appear in separate studies. We discuss several statistical issues related to this procedure, including the selection of a statistical model and statistical power for the comparison. To illustrate these points, we use the example of a meta-analysis of obesity prevention.

              The sixth report of the Joint National Committee on prevention, detection, evaluation, and treatment of high blood pressure.

              Racial and ethnic minority populations are growing segments of our society. The prevalence of hypertension in these populations differs across groups, and control rates are not as good as in the general population. Clinicians should be aware of these management challenges, taking social and cultural factors into account. Guidelines are provided for management of children and women with hypertension. In older persons, diuretics are preferred and long-acting dihydropyridine calcium antagonists may be considered. Specific therapy for patients with LVH, coronary artery disease, and heart failure are outlined. Patients with renal insufficiency with greater than 1 g/d of proteinuria should be treated to a therapy blood pressure goal of 125/75 mm Hg; those with less proteinuria should be treated to a blood pressure goal of 130/85 mm Hg. ACE inhibitors have additional renoprotective effects over other antihypertensive agents. Patients with diabetes should be treated to a therapy blood pressure goal of below 130/85 mm Hg. Hypertension may coexist with various other conditions and may be induced by various pressor agents.
