1 In this analysis the direction of effect is reversed. These figures have been confirmed as correct by the study authors. 2 Figures not presented in paper: Taken from Analysis 4.13. N/R ‐ Not reported QTcB ‐ QT interval corrected for rate and gender using Bazett's method. QTcF ‐ Qt interval corrected for rate and gender using Fridericia's method.
