Hi
thanks for query
all landmark trial have shown significant reduction in microvascular complication of
diabetes after good control of diabetes which is actually defined as
HbA1c less than 6.5%(without
hypoglycemia).it is HbA1c not blood
glucose which is true reflection of good control.
second important point is early part of diabetes(at onset) should be agreesively treated because it is early metabolic memory which determines microvascular complication.
i hope i have answered your query and waiting for your followup queries
