Concordance between downstream droplet digital polymerase chain reaction (ddPCR) and next-generation sequencing (NGS) for quantifying fusions in plasma cell-free DNA. Scatterplot of fusion molecules in plasma cell-free DNA detected by NGS (reads supporting the fusion divided by total reads sequenced) versus ddPCR (droplets supporting the fusion divided by total droplets with template) for the 17 samples (correlation coefficient, 0.859). The shaded region indicates the area in which the true regression line lies with probability 0.95 (95% confidence region). Mu, mutant droplets; WT, wild-type droplets.
