Figure 2From: Stromal, rather than epithelial cyclooxygenase-2 (COX-2) expression is associated with overall survival of breast cancer patients Kaplan-Meier analysis of overall survival and COX-2 staining in the cancer epithelial cells. COX-2 expression was detected with Ab1 (a), Ab2 (b) and Ab3 (c) antibodies and evaluated using the algorithms ALG1 (upper row), ALG2 (middle row) and ALG3 (lower row). 0 – low expression; 1 – high expression.Back to article page
