- - - - 19 = cummulative no of every event
      - 18.3 = cummulative length of follw-up
      - IR = The incident rate of events was 1.04 per person per year
- - - - cumulative no of all new events for all participants (watch, some may not have an event)
        
        8 new events/20 person-years at risk
        
        use figures from table to calculate
        
        IR (new event) = 8/20 = The IR of new events is 0.4 per person per year
        
        8 = cummulative no of events of all participants
        
        20 = cummulative length of follow-up for all participants
    - - cummulative no of every event recorded for each participant
        
        19 total events/ 20 person-year risk
        
        IR (all events) = 19/20 = The incident rate of events was 0.95 per person per year
        
        19 = cummulative no of every events
        
        20 = cummulative length of follow-up for all participants (2years x 10 participanst)
- - - - 8/10 = 80%
        
        The 2 year incidence of new events was 80%
