Cohort Study: Incidence Rate Scenario 3
Incidence Rate: Scenario 2
|
In cohort studies based on frequencies, we do not have information about exact time subjects spent in the study. Instead, we use the number of subjects at the beginning of the study and at the end. We then calculate risks based on frequencies. Twleve subjects started the study, and at the end four of them developed SS. |
