WebAug 27, 2016 · In relative risk terms the value of the risk for lung cancer death in the unexposed group is 1. Compared with that, the risk for lung cancer death in the exposed group is 22 times as great, and the attributable risk is the difference, which is 182.3/100,000 in absolute risk terms and 21 in relative risk terms. Figure 6-2 Risk of death from lung ... WebThe calculation of this measure assumes that the occurrence of disease in the unexposed group represents the baseline or expected risk for that disease. It further assumes that if the risk of disease in the exposed group is higher than the risk in the unexposed group, the difference can be attributed to the exposure. jesse white tumblers chicago

WebIn a particular study, researchers reported that there were 45% more cancer cases per 100,000 workers in the dye industry as compared to the rest of the population. In other words, that study found the RR (risk in exposed /risk in unexposed) of cancer for workers in the dye industry compared to the rest of the population was. Select one: a. 45%. WebNNT gives the RR some relevance in terms of the magnitude of clinical effect. ie. if the incidence of an adverse event = 0.06% & relative risk reduction = 0.33 the absolute risk reduction -> 0.02% and thus numbers needed to treat = 1/0.0002 = 5000. however, if the incidence of an adverse event was 6% the absolute risk reduction -> 2% and thus ...
