Figure 2.

Comparison of platelet-derived growth factor receptor-β (PDGFR-β) mRNA expression levels between gastric cancer tissue and adjacent normal mucosa. Box boundaries represent the 25th and 75th percentiles of the observed values, capped bars represent the 10th and 90th percentiles, and the solid line represents the median. P-values were calculated by the Wilcoxon signed-rank test. Expression levels of the PDGFR-β gene were higher in the cancer tissues than in the adjacent normal mucosa (P=0.009).
