Figure 2: Logarithmic scale of RNA content by tissue type and needle gauge in (a) lung tumors, (b) liver tumors, and (c) kidney tumors (N18 = normal tissue/18 gauge, T18 = tumor tissue/18 gauge, N20 = normal tissue/20 gauge, T20 = tumor tissues/20 gauge). The dark bar is the median, the box encompasses the 25–75 interquartile range (IQR), the dotted brackets are 1.5IQR, and dots are outliers.
