We present P-value for cancer vs non-cancer (Wilcoxon's test), cancer median peak height divided by non-cancer median peak height and area under the ROC curve. All of these peaks were also significant by LM and were not significantly associated with age, gender or H. pylori (P>0.05). Peaks arising from fragments of ITIH4 are marked with #.
