, reinforce the crucial role of early intensive glycaemic control in protection against micro- and macrovascular complications of diabetes. The benefits persist into the third decade after the completion of the trial, long after the difference in glycated haemoglobin between the intensive and standard arms has disappeared. This 'legacy effect' emphasizes the need for early diagnosis and aggressive management of diabetes from the time of its identification.
