Goodness of fit of the model is assessed by r. Note the improved effect at perfusion distance of 2 mm on deposition of power. Additionally, a drop-line chart (B) summarizes the observed relative frequency of an uncontrolled rise of impedance within two RFA durations (10 and 20 min) for the three values of perfusion distance. Note the lower rate of impedance rise during the procedure at a distance of 2 mm. In all cases, longer durations (20 minutes) were linked to a higher rate of impedance rise
