  1. Multivariable Cox proportional hazards models in breast cancer subgroups of the SCAN-B cohort. The hazard ratio with 95% confidence interval in italics and p value for the normalized log2 expression of indicated Ig mRNAs in each subgroup are shown. Overall survival was used as end point. The subgroups were based on either parameters used in clinical diagnostics today, such as ER and HER2 status, or the PAM50 subgroups as indicated. All models were adjusted for tumor size, lymph node status, patient age, and chemotherapy treatment. Models for subgroups based on hormone receptor and HER2 status were also adjusted for grade.
