Values represent (%). represents the total number of patients and the denominator for calculating the percentages in each column. The total of percentages in any column is higher than 100 as some patients were receiving more than one antihypertensive drug and hence included each drug class. ACE: angiotensin-converting enzyme; CAA: centrally acting agent.
