Main characteristics of the chronic care model group. The P value was 1 for all comparisons, as a result of the matching procedure. ARBs angiotensin receptor blockers, ACE angiotensin converting enzyme, HF heart failure
^aEqual prevalences in both groups as a result of the exact matching
^bThe majority of patients were treated with multiple medications at enrolment
