Comparison of P. falciparum IC50 values attained from pLDH and HRP-2 ELISA. Fresh P. falciparum isolates were tested for drug susceptibility using pLDH and HRP-2 ELISA, side by side. Median differences (Δ) are indicated below each pairwise comparison with values from the respective assays for each isolate joined by black lines. Unconnected dots are those where a corresponding value could not be obtained in either the pLDH or HRP-2 ELISA. Median IC50 and numbers of evaluable isolates from the respective assays appear above the X-axis, Significant P-values from the Wilcoxon pair test are indicated as *(P < 0.05), **(P < 0.01), ***(P < 0.001), ****(P < 0.0001)
