I want to know the answer to the following question:
In what year was thiazide antihypertensive drugs shown to help those with heart problems?
All the background I'm provided with is that "ACE inhibitors reduce the risk of new onset kidney disease [RR 0.71] and death [RR 0.84] in diabetic patients, irrespective of whether they have hypertension.". Is that enough to answer the question?
