WebHere, the nominal risk-free rate comes out to 8.2%. In a person with an AR of stroke of only 0.025 without treatment, the same treatment will still produce a 20% RRR, but treatment will reduce her AR of stroke to 0.020, giving a much smaller ARR of 2.5% 2% = 0.5%, and an NNT of 200. In the example above comparing the incidence of respiratory disease in smokers and non-smokers, the cumulative incidence (risk) of respiratory disease in smokers was 9/10=0.90 (or 90%), while in non-smokers the cumulative incidence (risk) was 7/12=0.58 (or 58%). This tool excludes people with diabetes because they already have a higher likelihood of heart disease and strokes. This improvement is called therapy impact.

Using the same cumulative incidences we can calculate the risk difference, an absolute measure of association. Risk difference is sometimes referred to as attributable risk and when expressed in percent terms it is also referred to as attributable proportion, attributable rate percent and preventive fraction. Suppose a study found that the cumulative incidence of coronary heart disease (CHD) was 3.2/1000 among subjects with hypertension and 1.2/1000 among those without hypertension. Another observation is that people tend to self-assess themselves as much more risk-averse than their quiz score indicates. Although more comprehensive and mathematical than the books by Douglas Altman and Martin Bland, "Statistical Methods in Medical Research" presents statistical techniques frequently used in medical research in an understandable format.
