Case numbers, incidence and summary of patient and tumour characteristics variables (those showing significant variation) by area-based deprivation stratum for female breast cancer in Ireland, 1999–2008.^a

See Figure 2 for treatment variation by deprivation stratum. *P<0.05, **P<0.01, ***P<0.001. #Age-adjusted relative risks for stratum 5 v 1, and for average per-unit change across deprivation strata 1–5, exclude unknown values for relevant patient, tumour and treatment variables. aFuller details of tumour and patient characteristics (e.g. finer age-groups) were used in statistical modeling of survival. bEuropean age-standardized rate (per 100,0000 women per year). cAge-standardized incidence ratio. dCases used for survival analysis exclude: diagnosis age <15 or >99; cancers preceded by another breast cancer or other malignant cancer (excluding non-melanoma skin cancers); death-certificate-only, autopsy-only and other cases with diagnosis = death date. eCases with known comorbidity status (based on hospital patient linkage) 2002–2008: 13039 (82.4%) of 2002–2008 total 15827. fDeprivation stratum was unknown for 1826 cases (not shown separately).
