Difference in anti-M 2 -R between patients with and without recurrence. The frequency of anti-M2-R in the patients with recurrent AF was significantly higher than that without recurrence (A) (72.0% versus 25.5%; P < 0.001). The geometric mean titer of anti-M2-R in the recurrent patients was also higher than that in the patients without recurrence (B) (1:153 versus 1:80; P = 0.002).
