Fig. 5

Intensities of five significant features that had higher intensities in cancer samples (a) and five significant features that had higher intensities in normal samples (b). The features are the most significant ones identified by univariate analysis (see Fig. 4 and Additional file 5: Table S3). The bottom and top of the coloured band represent, respectively, the 25th and 75th percentiles of the group, with the median denoted by the black line. The individual intensities for each group have been scattered with a random amount of x-axis positional variation
