Question

Which of the following about incidence are correct?

-The incidence rate assumes that everyone in the study population was followed during the period

-In a study with a population with a large amount of migration, the incidence rate would be more appropriate than the culmative incidence

-The calmative incidence can only be calculated in fixed populations

-The incident rate is more appropriate in dynamic populations -

-The culmtive incidence rate requires knowledge of time at risk for each member of the population

-The culmative incidence rate is the average of a population at risk over time

-The culmative incidence states the same when different durations are considered
