Correction to: British Journal of Cancer (2015) 113, 548–555. doi:10.1038/bjc.2015.204

It has been brought to our attention that there are errors in the paragraph ‘Assigning deprivation score’ on page 549 in the Materials and Methods section of the above paper published in volume 113, issue 3 (28 July 2015). The errors have now been corrected and the amended version of the paragraph in question reads as follows:

‘Two different ecological measures of deprivation were used according to the study period: a score based on Townsend’s system (Townsend et al, 1988) for women diagnosed with a breast cancer between 1989 and 2003 (40% of cases); the 2004, 2007 and 2010 scores of the Income Domain of the Index of Multiple Deprivation (IMD) (21.4%, 26.5% and 12.2%, respectively) for women diagnosed from 2004 onwards. The women were assigned a score according to their geographical area of residence at the time of their diagnosis (Communities and Local Government, 2008; Communities and Local Government, 2011; Neighbourhood Renewal Unit, 2004). Both the Townsend and IMD scores used Lower Super Output Areas (LSOAs, approximately 1500 people). The scores were split into five categories based on the quintiles of the national distribution of the areas.’
