Abstract
Kaplan-Meier curves provide descriptors of survival information for di fferent subgroups within a data set. Investigators frequently use thes e figures for descriptive comparison of the effect of a particular mea sure upon survival, When subjects enter a study at different ages and age is associated with survival, it is often desirable to adjust survi val information for age differences in the subgroups, This report disc usses several methods for age-adjustment of survival curves, including direct age-adjustment and proportional hazard modelling with age as a covariate.
