A cohort study examined the association between smoking and lung cancer after following 300 smokers and 700 non-smokers for 15 years. At the conclusion of the study the investigators found that 170 smokers had lung cancer and 120 non-smokers developed lung cancer. Find the risk of getting lung cancer among smokers and non-smokers.

What is the correct way to calculate relative risk?

Incidence rate of disease in those exposed to risk factor ÷ incidence rate of disease in those not exposed to risk facto

Incidence rate of disease in those not exposed to risk factor ÷ incidence rate of disease in those exposed to risk factor.

Control event rate divided by experimental event rate.

Lisinopril is a drug that lowers blood pressure in patients with hypertension. If a physician treats 400 patients with this drug and 90 of them suffer from peripheral edema over a period of 12 months. In the same course of time, he gave 400 patients a placebo and 22 of them suffered from peripheral edema. Calculate odds ratio
