Whilst we have also found trends between patient age and aspirin prescription, these narrowly failed to reach significance. It is likely that this result is due to the small numbers available for statistical testing once stratified into age appropriate groups, and an adequately powered study is likely to have confirmed such a relationship. There is limited evidence to suggest that this lack of prescription is detrimental to patient care, and indeed this may be clinically appropriate decision making. As outcome data was not available within our study, this is unknown, however it would be interesting to explore this relationship in future work.
