Figure 6

Forest plot showing the mean difference of change in diastolic blood pressure between minerals (calcium, magnesium, potassium) and placebo. T represents the sample size of the treatment (supplement/mineral) group and C represents the sample size of the control (placebo) group. The pooled mean difference is given in mm Hg with its 95% CI. The weighted mean difference in mm Hg and its 95% CI is given for each study. A graphical representation with the weighted mean difference and its SE is also given for each study.
