Interval 0—starting at current age | Interval t-1 | Interval t | |
---|---|---|---|
Risk of CVD event in age interval | 0 | at−1 | at |
Risk of non-CVD death in age interval | 0 | bt−1 | bt |
Proportion of original cohort having non-CVD death in interval | 0 | ct−1 | ct=et−1 x bt |
Proportion of original cohort having CVD event in interval | 0 | dt−1 | dt=et−1 x at |
Proportion surviving free of CVD at end of interval | 1 | et−1 | et=et−1−ct −dt |
Cumulative proportion with CVD events by end of interval | 0 | ft−1 | ft=et−1+dt |
Cumulative proportion dying from non-CVD causes by end of interval | 0 | mt−1 | mt=mt−1+ct |
Note that et+ft+mt=1 for all t.
CVD, cardiovascular disease.
