The weights are based on the age structure in Greenland for both the observed and the expected number of deaths, and the rates are therefore age standardized according to our definition. Notice that the SMR depends on which set of weights we use since the age-specific mortality rate ratios vary largely with age. They are especially higher in Greenland than in Denmark among the young and by selecting the population in Greenland we give more weight to the young.
Cardiovascular diseases, but what would the occurrence have been had they not taken the hormones? That is of course not observable since nobody can be using and not be using hormones at the same time, but it is possible to imagine that these women had not used the hormones. To estimate what the occurrence would have been had they not taken the hormones, we unfortunately have to use a different group of women who did not use the hormones under study. We select these women in the hope that they will provide the expected disease occurrence for the exposed, had they not been exposed.

Often, they will have to work with secondary data that only approximate the information needed to make exact calculations.
