A case-control study is conducted to estimate the association between sedentary lifestyle and stroke. Researchers enroll 100 patients who had a stroke in the past year and 400 patients who have never had a stroke. Researchers conclude that the prevalence of stroke in the past year in the population is 20%. This conclusion is: Correct Incorrect because prevalence cannot be estimated from a case-control study Incorrect because the prevalence is 25%
