Figure 5. Dose‐response relationship between changes in blood pressure and combined docosahexaenoic acid (DHA)+eicosapentaenoic acid (EPA) intake of the studies stratified by the mean of age.

Marginal average dose‐response curve (solid line) with 95% point‐wise CIs (dashed lines) estimated by a 1‐stage random‐effects restricted cubic spline model, using 0 g/d as the referent, among participants with a mean age ≥45 years or <45 years. n indicates the number of the included study.
