On the other hand both the antibodies Ab2 and Ab3 yielded data demonstrating statistically significant correlation between COX-2 expression and survival with P2 = 0.007 and P3 = 0.032 respectively for the tumours selected for high COX-2 expression using ALG1 and with P2 = 0.043 and P3 = 0.02 for the same set of data analyzed with ALG2. This evidence concerns the gene ALG2 and neoplasm.
