The death rate per 100,000 for lung cancer is 7 among non-smokers and 71 among smokers. The death rate per 100,000 for coronary thrombosis is 422 among non-smokers and 599 among smokers. The prevalence of smoking in the population is 55%.(1). What is the RR of dying of lung cancer for smokers versus nonsmokers? Is this how you do it?
| Lung Cancers (Yes ) | Lung Cancer (No) | Total | |
| Smokers | 71 (A) | 54,929 (B) | 55,000 |
| Non-Smokers | 7 (C) | 44,993 (D) | 45,000 |
| 78 | 99,922 | 100,000 |
.55x 100,000 = population of smokers 55,000
55,000-71= those who do not have cancer
[71/(71+54,929)] / [7/(7+44,993)]
71/55,000/7/45,000
0.0012909091/ 0.0001555555= 8.30 RR
