Cohort Study: Incidence Rate Scenario 1
Incidence Rate: Scenario 1
Assumptions:
Since we don't know the exact dates of exit, we assume that in each year when a subject exited he/she contributed only half a year to person-year experience of the cohort.
Calculation of person-years:
Contributed to follow-up in year 1:
Contributed to follow-up in year 2:
Contributed to follow-up in year 3:
Contributed to follow-up in year 4:
Contributed to follow-up in year 5:
Contributed to follow-up in year 6:
Contributed to follow-up in year 7:
Total PYO accumulated through 7 years of follow-up:
