  1. The chloroquine-sensitive strain 3D7 was tested and gave adequate results <100 nM [44]. The difference of values for each molecule for 3D7 was significant excepted for artesunate (p = 0.35). p value indicates the significance of the difference of geometric means of the same molecule between 2012 and 2013
