  • ACEI–angiotensin-converting enzyme inhibitors, ARB–angiotensin receptor blocker, BB–β-blocker, CCB–calcium channel blocker, CI–confidence interval.

  • * Meaning 1 or 2 additional classes (eg, ACEI/ARB + 1 indicates ACEI/ARB and either a diuretic, a BB, or a CCB, etc). A patient taking more than 1 drug class is counted in all relevant categories; therefore, not all percentages add up to 100.
