MAGEA4 and neoplasm: The weakly positive correlation between the rate of cells positive for NY-ESO-1 and tumor size was moderate (r = 0.46, p = 0.28 (Pearson’s test), p = 0.51 (Spearman’s test), p = 0.17 (Multiple regression test), Figure 3c) that between the rate of cells positive for MAGE-A4 and tumor size was also moderate (r = 0.61, p = 0.61 (Pearson’s test), p = 0.65 (Spearman’s test), p = 0.27 (Multiple regression test), Figure 3d).
