Figure 2 PAF-free rate curves according to Kaplan-Meier analysis in patients with and without an abnormal P-SAE (P-SAECG) (Ad >132 ms and LP₂₀ <2.3 µV). The bold line (29 patients with the abnormality) and the narrow line (46 patients without the abnormality) show the PAF-free rates. The numbers at the bottom are the number of patients in each group at risk for the event (PAF attack) at study entry and after each 100-day period. The PAF-free rate was significantly lower in patients with rather than without an abnormal P-SAECG.
