Yet looking at larger data sets, such as the MRFIT screenees study in some 342,000 non diabetic and 5,000 diabetic subjects, the slope of the influence of blood pressure on coronary heart disease mortality is actually somewhat shallower in diabetic subjects than in non diabetic subjects. Having said this, one must not forget that, in absolute terms, the excess risk attributed to hypertension in diabetic subjects substantially exceeds that in non-diabetic subjects as they are starting from a substantially higher baseline risk.
