A recent analysis of data from the UK Prospective Diabetes Study has also compared observational and intervention data, and suggests that the interventional effects of blood pressure lowering on reducing risks of stroke and coronary heart disease exceed the attributable risks consequent upon elevations in blood pressure by the same amount, although the confidence intervals are wide. These findings, of a greater benefit attributable to blood pressure lowering than can be attributed to the damage of blood pressure elevation, have been seen particularly in studies of treatment of isolated systolic hypertension, and studies in diabetic patients.
