Public health workers tend to focus on avoidable causes which would include both the removing of the wood as well as being careful with matches. If removing the wood would have prevented the fire that cause is as good as any other cause.
In our component causal model all component causes in a causal field are necessary causes within this field, but we can define the last component cause (if it is known), the one that onsets the disease, as the cause of interest for the etiologic fraction. Notice that if the causal field consists of stationary genetic factors and an external toxic exposure that onsets the disease, we can emphasize this cause as we did when we said the fire was not caused by the presence of wood but by the lighting of a match.
There are different weights to select from and this choice should be made with care. Unless the relative mortality rates are the same in all age groups, the selection of weight will affect the result we get. 3. In this table, we take the observed number of deaths in the population of Greenland (160) and estimate how many deaths we would have expected had they had the same age-specific mortality as in Denmark. 1. 1 a If they had the same mortality rates as in the Danish population. 1 or, the mortality rate is on average 54% higher in Greenland than in Denmark.
