what is the incidence density rate (express as #HD per 100 patient-years) for non-coffee drinkers?
Homework Answers
Incidence density rate is the number of new cases in a specified time period divide by total number of person -time when at risk .
IR in this case = Number of new cases of non -coffee drinkers over a time period ÷ by total number of person in the same time period × 100
