Document Summary

None of the subjects has the outcome of interest at the beginning of the follow up period. The association between exposure and outcome is based on the. Incidence of the outcome in exposed and unexposed groups (watch for the outcome separately those groups/ takes time/ the longer it takes the more expensive, and greater risk for dropout) In a cohort, we can control for confounders and bias more effectively than in a case control study. Validity- truth- prospective cohort has more validity than a case control. We get an incidence of the outcome in the exposed group and the unexposed group. We ask if it greater in those who r exposed or vice versa. We translate that incidence into a risk value. Start with people who have the outcome/condition and ask them to go back (medical records or asking questions) We cannot calculate the incidence of outcome for this case because everyone has the outcome.
