Figure 2.
Treatment effect changes in resting diastolic blood pressure (DBP). The black filled squares, sized according to the weight contributing to the overall effect, represent changes in DBP from each study while the left and right extremes of the squares represent the lower and upper 95% confidence intervals for changes in DBP from each study. The black diamond represents the pooled mean change in resting DBP while the left and right extremes of the diamond represent the pooled lower and upper 95% confidence intervals for changes in DBP. The dashed vertical line represents the pooled mean effect for changes in DBP while the solid vertical line represents the zero (0) point.
