I found it all very interesting, especially the section on blood pressure controls, the section on Aspirin, and the section on Metformin and heart benefits.
Metformin - from how I read it, this is beneficial for the heart COMPARED WITH other diabetes drugs. This could mean it is the other drugs causing heart problems whereas Metformin doesn't, rather than Metformin being beneficial in itself.
Blood pressure - it seems the 140/80 target appears too tight and more people die with BP under 110/70, and the bottom figure should be not much less than 70.
Aspirin should not be prescribed to diabetics, full stop.
I need to read it all again.
