Figure 2. Relative Success of AF Conversion to Normal Sinus Rhythm: Sotalol versus Amiodarone Each row shows the name of the first author of the publication followed by the reference number in parenthesis, the relative success (Risk ratio: “risk” of successful AF conversion) with 95% confidence interval (95% CI), and the significance (p) of the difference in success. The number of patients of whom AF converted and the total number of the patients (Event/Total) in the sotalol and the amiodarone arms are also shown for each study. The graphic presentations of the results are shown on the right (Forrest Plot). The boxes represent the relative success and the lines represent the 95% CI for individual studies. The size of boxes and the thickness of lines reflect the weight of a study in the analysis. The result of the meta-analysis is shown in the last row (bottom) numerically, as well as graphically (the diamond in the Forest Plot). Test for heterogeneity: I2 is the percentage of total variation in study estimates that is due to heterogeneity (16%.). The studies effect sizes were homogenous, thus the fixed effect model was employed for meta-analysis. The combined relative success is 0.947 (95% CI: 0.837 to 1.071, p=0.385), indicating no difference between the two drugs in pharmacologic conversion of AF .
