Further details of model C (Table 2): other patient and tumour factors influencing breast cancer survival (in a model assessing the influence of area-based deprivation status), 1999–2008.

Only factors which contributed significantly to model-fit are showna; hazard ratios for age, TNM and grade are not shown, as the model shown in parentheses for age, TNM and grade are from simpler, adjusted but unstratified models (the more definitive model was stratified for those variables).aMarital status and HER2 status excluded as they did not significantly contribute to model-fit); Charlson Index of co-morbidity (available for 82% of cases 2002–2008) excluded as it did not contribute significantly to model-fit (in 2002–2008 sub-analysis); standard errors adjusted for clustering by region of residence. Models adjusted for (or stratified by) coarser groupings of variables tabulated had a poorer fit to the data.* PFurther details of model C (Table 2): other patient and tumour factors influencing breast cancer survival (in a model assessing the influence of area-based deprivation status), 1999–2008.
