Figure 8 Variation of (A) percentage area stenosis and (B) pressure drop coef-ficient and resistance index over time for arteriovenous fistulas created in a pig model[70]. AS: Area stenosis; C_p: Pressure drop coefficient; R: Resistance index. The t/d in the x axis stands for time (days). © 2014, Copyright the Authors.
