for analyses of tumour incidence was 31 December 2009
for all 10 regions (corresponding to 10 cancer registries),
except for the North West (Mersey) region and
Scotland, where it was 31 December 2008 (as registrations
were incomplete after that date). For vascular disease
incidence, hospital admissions data were available
in England until 31 March 2008 and in Scotland until 31
December 2008, with follow-up ending on these dates.
