|Multivariate Cox regression analysis on disease-specific survival in 80 invasive breast cancer patients|
|Disease specific survival|
|Axillary lymph node status||0.03||0.35||1.03||0.53-2.04||0.64|
|Pathologic tumor size||0.001||0.01||0.10||0.98-1.02||0.97|
* Determined by chi-square test.
β: Regression coefficient; SE: standard error of β; HR: hazard ratio; and CI: confidence interval. BRE: Bloom, Richardson, Elston/ Ellis; ER/PR: Estrogen/progesterone receptor. Coding of characteristics: BRE, HER2/neu status, Axillary lymph node status, ER/PR and CCNB2 were coded as 0 (negative) and 1 (positive) respectively. Pathologic tumor size was coded as 1 (0-20mm), 2 (>20-50mm), and 3 (>50mm).
