Suppose all the matched pairs in Table 10.27 are considered. What method of analysis can be used to test whether there is an association between widowhood and mortality? 

Mental Health

A study was performed in Lebanon looking at the effect of widowhood on mortality [14]. Each of 151 widowers and 544 widows were matched to a person married at the time of widowhood and of the same age (± 2 years) and gender. The people in the matched pairs were followed until one member of the matched pair died. The results in Table 10.27 were obtained for those matched pairs in which at least one member had died by 1980. 

Table 10.27: Effect of widowhood on mortality

 

^an₁ = number of pairs in which the widowed subject is deceased and the married subject is alive.

^bn₂ = number of pairs in which the widowed subject is alive and the married subject is deceased.
