A critique of hypertension treatment trials and of their evaluation

Progressive improvements in antihypertensive drug therapy over the past four decades have provided clear benefits in limiting cardiovascular complications.

The consequence has been a devaluation of the very real worth of prophylactic drug therapy for hypertension.
