*Prescribed drugs contributing to each co-prescribing profile cluster are marked with “•” Concurrent prescribed ATC classes marked with “•” may not be at the same ATC level. †Co-morbidity prescribing profiles based on prescribed ATC class have been reproduced in decreasing order of frequency until a cluster containing each of the top 10 that have frequencies above 0 have been identified.
