Ex vivo sensitivity of P. falciparum to chloroquine and lumefantrine. Bold lines represent median IC₅₀s. Faint horizontal lines represent the 25th and 75th interquartile range. Mean IC₅₀ for chloroquine were 24.8 nM, 24.9 nM, 17.4 nM, 22.6 nM and 23.1 nM in 2013, 2014, 2015, 2017 and 2018, respectively; and for lumefantrine, 20.8 nM, 20.5 nM, 32.0 nM, 28.6 nM and 21.0 nM in 2013, 2014, 2016, 2017 and 2018, respectively. Cut-off sensitivity is based from literature
