 Estimated cumulative numbers of women in study population expected to develop, or die from, invasive cervical cancer during each test period and for further 15 years into future, without screening (adjusted rates) and with screening (unadjusted rates). Expected deaths with screening beyond 1996 assume 60% of deaths after 1996 are prevented by screening
