Graphical representation of differentially-expressed plasma proteins between all CRC stages (I–IV) compared to healthy controls. a Box plots for differentially-expressed proteins between healthy control and CRC stages I–IV. *p < 0.05, **p < 0.005, ***p < 0.0005 and ****p < 0.0001 calculated using unpaired t-tests. Distribution (b) of 31 potential candidates identified from four biomarker discovery experiments superimposed on the SWATH reference library protein concentration curve plotted against protein abundance rank. The color key on the top-right side shows proteins identified from different biomarker discovery experiments
