A comparison of Poisson regression models fitted to multiway summary tables and Cox's survival model using data from a blood pressure screening in the city of Bergen, Norway.
Multiplicative models for the association between blood pressure and coronary heart disease mortality in 5201 men aged 40-49 years at time of examination were compared. Piecewise exponential models fitted to summary tables formed by cross-classification by three systolic and three diastolic blood pressure groups, two age groups and three time intervals gave results close to the Cox model for continuous data. The parametric integrated baseline hazard functions estimated from grouped data were close to Breslow's nonparametric estimate in the Cox model.
