NOTE: Characteristics were included in the models if P ≤ 0.05 by univariate analysis in at least one cohort (Table 1) or the combined cohort. Cases were excluded if all characteristics were not reported. The ORs were not statistically significant if basal-like and luminal B cases were considered as one group. Values in bold were statistically significant.
