Comparison of the ablation parameters between two groups
Figure 2 shows the comparison of the ablation parameters between the touch up sites and control sites. All parameters at the touch up sites were significantly lower than those at the control sites (touch up site vs. control sites; energy delivery time, sec, 20.3 [12.3-21.7] vs. 21.6 [19.8-25.2], p=0.0003; power, W, 23.5 [15-24] vs. 24 [20-25], p<0.0001; CF, g, 7 [6-10.8] vs.11 [9-15],p<0.0001; FTI, 126.5 [99.3-208.8] vs. 244 [183.5-340.5],p<0.0001; AI, 277.2±21.8 vs. 350.2±42.8 , p<0.0001). The median value of the AI at the control sites was 350 and the maximum value of the AI at touch up sites was 308.
