Effects of treatment on morbidity in hypertension. II. Results in patients with diastolic blood pressure averaging 90 through 114 mm Hg

·1970·JAMA

Abstract

Three hundred and eighty male hypertensive patients with diastolic blood pressures averaging 90 to 114 mm Hg were randomly assigned to either active antihypertensive agents or placebos. The estimated risk of developing a morbid event over a five-year period was reduced from 55% to 18% by treatment. Terminating morbid events occurred in 35 patients of the control group as compared to 9 patients in the treated group. Nineteen deaths related to hypertension or atherosclerosis occurred in the control group and 8 in the actively treated group. In addition to morbid events, 20 control patients developed persistent diastolic levels of 125 mm Hg or higher. Treatment was more effective in preventing congestive heart failure and stroke than in preventing the complications of coronary artery disease. The degree of benefit was related to the level of prerandomization blood pressure.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
