aThe values are numbers (percentages)
bDependency on activities of daily living (DADL) measured with the Barthel index, a score of ≤ 60 is considered a severe dependency, 60–90 is considered moderate dependency and > 90 almost no dependency[10]
cOnly the high-risk medication (medication with a high risk for hospital (re)admissions in patients) with significant differences in proportions are displayed
