Changing the glucose cut-off values that define hypoglycaemia has a major effect on reported frequencies of hypoglycaemia

Abstract

The glucose cut-off point defining hypoglycaemia greatly affects the reported frequency of hypoglycaemia. When hypoglycaemia is to be defined by a predetermined glucose level, to have clinical relevance the cut-off should be set at a lower level than the threshold of 3.9 mmol/l proposed by the American Diabetes Association.
