Fig. 2From: High-throughput malaria serosurveillance using a one-step multiplex bead assayComparison of assay median fluorescence intensity minus background (MFI-bg) signal by both assay protocols and sample types. Relationship in MFI-bg values for the eight malaria antigens between two protocols and two sample types visualized as LOESS curves with cubic interpolation and 95% confidence limits in shading, with y = x reference as a hashed lineBack to article page
