Table 1.

The top three association rules that our explanation ranking method produced for the first selected patient (patient 1). This patient satisfied condition 1.

Rank	Association rule	Confidence of the rule			Commonality of the rule (n=1184), n (%)
		Total, n	Value, n (%)
1	The patient had 2 or 3 EDa visits related to asthma during the past year AND the patient was prescribed between 7 and 11 distinct asthma medications during the past year AND the patient was prescribed between 5 and 7 distinct asthma relievers during the past year AND the patient had ≥1 active problem in the problem list during the past year → The patient will likely have ≥1 inpatient stay or ED visit for asthma in the succeeding 12 months.	46	24 (52.17)	24 (2.03)
