Five-year age-adjusted case fatality rates by stage at diagnosis in those aged ≥66 diagnosed April 2007-March 2012 and the possible reduction if the stage distribution of women with cytology in the 12 months prior to diagnosis was achieved.

^1a100 minus 5-year % relative survival for women aged 70+, SEER 1988–2001 (see reference 15).

^1b100 minus 5-year % relative survival (all ages), Anglia 2002–2006 (http://www.cancerresearchuk.org/health-professional/cancer-statistics/statistics-by-cancer-type/cervical-cancer/survival#heading-Three).

²Assuming the stage distribution for those with stage not recorded did not depend on having cytology in the year prior to diagnosis and using SEER survival.

³Assuming the stage distribution for those with stage not recorded did depend on having cytology in the year prior to diagnosis and using SEER survival.

⁴Ignoring those with unrecorded stage and using survival from Anglia.

^*78 of these cancers were part of the cohort aged ≥70 and 10 of the cohort diagnosed within a year of their first cytology test aged 40–69 in Table 1.
