Impact of mammography on breast cancer mortality in women aged 40–49 | Impact of faecal occult blood screening on colorectal cancer mortality in people aged 40–49 | |
---|---|---|
Comparing different types of intervention. Comparison of the impact on mortality of mammography as a screening method for breast cancer in women aged 40–49 years and faecal occult blood testing as a screening method for colorectal cancer in people aged 40–49 years in Australia. NNT is the reciprocal of the absolute risk reduction. Pe is the proportion of the population eligible for the intervention and Pd is the proportion of the total population in the age range 40–49 years. PIN has been rounded to the nearest 100 | ||
