Figure 7From: Haemodynamic consequences of changing potassium concentrations in haemodialysis fluids Total peripheral resistance. Total peripheral resistance 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: < 0.05, < 0.05 and ns respectively.Back to article page
