Cox proportional hazard ratios. Estimated coefficients of overall survival on breast cancer subjects. Calculated are the corresponding hazard ratio (HR), 95% confidence interval (CI) of the hazard ratio, and p-value in uni- and multivariable Cox proportional hazard analysis for CTC-status with negative as reverence, and T-, N-, and M-stage at initial diagnosis.
