  1. Ovarian (C56)/tubal cancer (C57.0) and other malignant neoplasm of skin (C44) have been excluded. Average time on trial at censoring (1st June 2009) = 5.55 yrs/woman. Note the number of 'Women years' relates to individual causes and not to overall mortality due to exclusion of Northern Ireland women. Italicised values have 95% confidence intervals not containing 100.
