Fig. 3From: Determination of temporal reproducibility and variability of cancer biomarkers in serum and EDTA plasma samples using a proximity extension assaySerum-to-plasma ratio in our study and as reported by Olink on linear normalized protein expression (NPX) scale. Red lines indicate boundaries of acceptance (25% quartile (Q) + 1.5 interquartile range (IQR) and 75% Q + 1.5IQR). Blue points indicate serum-to-plasma ratio reported by Olink. Data were not reported by Olink for 6 proteins: KIR3DL1, MUC-16, TNF, IL15, LAG3, IFN-gammaBack to article page
