(Cox proportional models for breast cancer specific mortality by delay in first adjuvant therapy, radiation therapy and chemotherapy).
^aPerformed in three separate Cox regression models, ^bFor stage I-III invasive breast cancer adjusted for age, ethnicity, stage of disease (i.e. tumour size and number of positive lymph nodes), tumour grade, oestrogen receptor status, lympho-vascular invasion, year of diagnosis, comorbidity score and receipt of adjuvant therapy.
