Figure 2From: Mass spectrometry protein expression profiles in colorectal cancer tissue associated with clinico-pathological features of disease Probability distribution of marker peaks distinguishing tumour from normal mucosa. Spectra from all 64 tumour and normal tissue samples were analysed by Comparative Gene Marker Selection [28] using the SNR test statistic to identify peaks (features) that discriminate tumour from normal tissue. The feature P histogram shows the number of peaks (occurrences) that fall within binned P values.Back to article page
