7. Stable diabetes therapy for at least 3months as defined as:

   • No increase in dose of diabetes medications by more than two-fold or
   • No new agents added within the previous 3 months
8. Stable doses of angiotensin converting enzyme (ACE) inhibitors or angiotensin AT(1)-receptor blockers (ARBs) for at least 3 months.
