  1. Data are percentages. Numbers in parentheses are 95 % confidence intervals. AF atrial fibrillation, ePCWP estimated pulmonary capillary wedge pressure, PPV positive predictive value, NPV negative predictive value
  2. Note that the positive predictive values are useful to estimate the probability of successful AF ablation
