Forest plot demonstrating the (A) mean Tpeak – Tend intervals in the event-negative group (top panel), event-positive group (middle panel) and difference between both groups (bottom panel) in acquired QT prolongation, and (B) mean Tpeak – Tend/QT ratios in the event-negative group (top panel), event-positive group (middle panel) and difference between both groups (bottom panel) in acquired QT prolongation.
