Fig. 1From: The effect of an anti-malarial herbal remedy, Maytenus senegalensis, on electrocardiograms of healthy Tanzanian volunteersQTcF profiles (A) and change in QTcF from predose over time (B) in volunteers received Maytenus senegalensis. Dashed lines in pane A represent individual volunteers who received 400 mg once (group 1, green line), 600 mg once (group 2, orange line) and 800 mg every 8 h for 4 days (group 3 and 4, blue line). Dots in panel B represent individual observations. QTcF = Fridericia-corrected QT interval. Dashed red line represents a change in QTcF from pre-dose of 30 ms. Solid gray line represents a change in QTcF from pre-dose of 0 msBack to article page
