a Hazard ratio, estimated from Cox proportional hazard regression mode. b Confidence interval of the estimated HR. Results are based on 1000 bootstrap samples and obtained after the Bias corrected and accelerated (BCa) approach. c Multivariate model adjusted for age, HER2, LN, Size, Grade, Stem cell. d Multivariate model adjusted for age, ER, PR, HER2, Size, Grade, Stem cell. e Multivariate model adjusted for age, ER, PR, HER2, LN, Size, Grade. Bold: highlights the significance of the test.
