A Correlation of Notch-1 and PTEN co-expression in each of the three breast microarray data sets as calculated by Spearman’s correlation coefficient
B Co-expression of high Notch-1 and low PTEN regardless of HER2 status (all BC) correlates with an overall decrease in patient survival time in the Curtis Breast dataset as determined by the Cox proportional hazards model. The log-rank test p-value = 0.001262
C In the HER2+ dataset, the overall significance of Notch-1, PTEN, and HER2 is 3.11 × 10−5 by the Log rank test. The overall significance of Notch-1 and PTEN based on HER2+ status is 0.022, by the likelihood ratio test
