The objective of the Trial of Antihypertensive Intervention Management (TAIM) was to
determine the efficacy of dietary management and/or drug therapy, namely thiazide-like
diuretics or a beta-blocker, in the control of mild hypertension. Additionally, the
Continuation of the Trial of Antihypertensive Intervention Management (COTAIM) tested the
effects of long-term weight reduction, and sodium/potassium changes added to weight
reduction, as well as the original drug treatment, on the failure rate of blood pressure
control.
