Pooled dose–response association between potassium intake and risk of stroke (solid line) in a meta‐analysis modeling potassium intake with restricted cubic splines in a multivariate random‐effects model, with (A) and without (B) adjustment for blood pressure. The relative risks are plotted on the log scale, with 25 mmol of daily potassium intake serving as referent category. Dashed lines represent the 95% CI for the spline model.
