Epidemiologia | Como montar uma tabela 2x2

This video demonstrates how to fill out, interpret, and use 2x2 tables using the following example: A cohort study was conducted to study the association between obesity (exposure) and myocardial infarction (outcome). The study was conducted on a sample of elderly individuals, starting when they were 60 years old and ending after 10 years of follow-up. A total of 400 individuals were recruited for the study, of whom 50 had already experienced at least one myocardial infarction by age 60. Among the individuals followed, 30% were obese at age 60. The cumulative incidence of myocardial infarction in the sample was 10%, with 10 non-obese individuals experiencing myocardial infarction during the study period. Calculate the relative risk.
