[Cut-off level of glycosylated hemoglobin indicating the development of complications in type 2 diabetes mellitus]. / Cut-off del livello di glicoemoglobina e complicanze del diabete mellito di tipo 2.

Prevention of chronic complications is very important in the management of type 2 diabetes, and the availability of a laboratory test individuating at risk subjects should have a marked usefulness. This study sought by the method of ROC curves the cut-off of glycated haemoglobin discriminating the subjects with microvascular, neurologic and renal complications from those without. The cut-off was identified at a glycated haemoglobin level of 7.95, showing a sensitivity of 74.8% and a specificity of 73.3%, which makes it a possible tool for evaluating the risk of complications in type 2 diabetes.
