Figure 2.

Results from meta-analyses of randomized controlled trials examining eicosapentaenoic and docosahexaenoic acids (EPA+DHA) provision and (a) systolic blood pressure and (b) diastolic blood pressure among hypertensive subjects. The squares represent average change in blood pressure in individual randomized controlled trials, or individual trial strata, with 95% confidence intervals (CIs). The diamond represents the pooled summary estimate. Knapp (a) is a higher-dose subgroup, and Knapp (b) is a lower-dose subgroup.
