^{a} Tumor variable that showed a statistically significant association with patient survival times in the univariate analysis. There were 202 patient cases available with full data sets. Only comparison between patients with involved lymph nodes, all tumor sizes (T_{1}-T_{4}), all histological grades (I–III), staining for OPN, c-erbB-2, ER_{α} and p53 were made.
^{b} Value of β parameter in the Cox’s multiple regression analysis (“Materials and Methods”).
^{c} SE of β.
^{d} Cox’s statistic χ^{2}.
^{e} Regression coefficient for the variable.
^{f} Probability from Cox’s statistic χ^{2}, 1 d.f. in each case. Overall χ^{2} = 84.1, 5 d.f., P<0.0001; residual χ^{2} = 2.52, 5 d.f., P = 0.77.
^{g} RR for survival and 95% CI from multivariate analysis.
