Table 2. Multivariate analysis of prognostic variables in ER-negative breast cancer with CIN grouped by MCD.
Analysis results of the multivariate robust Cox Proportional- Hazard Regression for all ER-negative patients with covariates size, grade, HER2 status, chemotherapy, node status and MCD4 versus all other MCD cohorts taken together. The table shows the hazard ratio, upper and lower 95% confidence limits and P values for each covariate. The covariates are ranked by P values. Significant covariates are labelled by asterixes.
