Does salt substitute reduce stroke, major cardiovascular events, and death from any cause in persons with a history of stroke or who are 60 years of age or older with high blood pressure?

Among persons who had a history of stroke or were 60 years of age or older and had high blood pressure, the rates of stroke, major cardiovascular events, and death from any cause were lower with the salt substitute than with regular salt.
