Fig. 1From: Assays for quantification of male and female gametocytes in human blood by qRT-PCR in the absence of pure sex-specific gametocyte standardsThe plots show log10 gametocytes/mL by ddPCR and qRT-PCR. The solid black line represents the fitted Passing–Bablok regression line. The 95% confidence bounds, in grey, were calculated using the bootstrap quantile method. The female pfs25 assay is shown to the left and the male pfMGET assay is shown to the right. The reference standard was ddPCRBack to article page
