Figures

Figure 1
Figure 1. Concordance of mutations in CH, MDS, and AML between biofluids and sensitivity/specificity of multiple biofluid calls.
(A) Scatter plot and box plot of VAFs in buffy coat versus saliva for CH, showing that saliva has lower VAFs than buffy coat (P = 4.9 × 10–5, 95% CI [–4.21, 1.90]). (B) Scatter plot and box plot of VAFs in buffy coat versus cfDNA in CH, showing nonsignificant differences in buffy coat and cfDNA VAFs (P = 0.11, 95% CI [–2.99, 3.13]). (C) Scatter plots of each AML and MDS sample, comparing the buffy coat and cfDNA VAFs. (D) Dot plots of the VAFs in buffy coat versus cfDNA in AML, CH, and MDS. (E) Observed sensitivity when incorporating 1 (single; yellow), 2 (duo; green), or 3 (trio; blue) biospecimens to establish a mutation call. (A–C) The gray line represents x = y. Comparisons were done using paired 2-tailed t tests. Boxes indicate interquartile range, middle bars denote the median, whiskers represent minimum and maximum values, and dots indicate outliers.
