Hypothetical patient's incidence rate for lung cancer in 120 Thai people's information is extremely. For groups of people who do not smoke have a rate of 30 items per hundred thousand. Best in the group, there are those who continue to smoke daily, with 330 rate and risk of lung cancer in people who smoke, compared with a group who does not smoke is equal to. RR = (330/100,000 ) ( 30/100,000 ) = 11 The Thai population and smoking 30 per cent (P) Therefore, If we assume that 30 percent of the population smoking, stop smoking, and contributed to the emergence of the rate of lung cancer patients-in this group will be reduced from 330 items per hundred thousand to 30 items per hundred thousand. ARP = 0.3 ( 330/100,000 - 30/100,000) (120/100000) = 75% Or think of the formula. ARP = P ( RR - 1) x 100 P ( RR - 1 ) + 1 = 0.3 ( 11 - 1 ) x 100 = 75% 0.3 (11-1) + 1 It means that 75% of patients with lung cancer in the Thai public has caused due to smoking (therefore, if those who smoke become someone who is smoking, and reduce the number of people as many as lung cancer. Worth it or not, it has to be compared with other job protection rong) adioactive material and the illness.
