Figure 8From: Haemodynamic consequences of changing potassium concentrations in haemodialysis fluids Stroke volume. Stroke volume as a function of dialysis tertiles comparing treatments with the two potassium (K) concentration cut-off points in the dialysate (high = K+1 and low = K-1). P for the 1st, 2nd and 3rd tertiles: ns.Back to article page
