Presence of single nucleotide mutations detected in blood in other W115 tissues. Box plot of the VAF values for the 214 confirmed somatic mutations detected in blood for a variety of other tissues. On each box, the central mark is the median VAF; the edges of the box are the 25th and 75th percentiles, the whiskers extend to the most extreme data points not considered outliers, and outliers are plotted individually as red crosses.
