The average % methylation calculated from three independent qPCR and dPCR measurements of three independent bisulfite conversions of a panel of methylated/unmethylated DNA standards; Data for dPCR show measurements from the P14_M assay used in singleplex and for the P14_M and P14_M2 assays used together in duplex, showing the % methylation for each assay when analysed individually and with the estimated targets combined (P14_M + P14_M2). Symbols denote statistical comparisons using a One-Way ANOVA test. All comparisons between samples with expected differences in methylation of ≥ 50% were significant at the level of p < 0.05 (with the exception of 50% vs. 100% methylation with MethyLight P14_M2 Duplex) and are not shown; all comparisons between samples of differences between 0-40% expected methylation that are significant (p < 0.05) are shown with pairs of the same symbols (*^,¥,+,‡) denoting which two samples were compared, e.g. for dPCR P14_M2 duplex, only the 10% and 50% methylated (expected % methylation) data points were significantly different from each other at the level of p < 0.05.
