1) To assess the various definitions and time points of measurement of hypoglycaemic events in randomised controlled trials (RCT) on long-acting insulin analogues in people with type 1 diabetes mellitus.
2) To assess if the risk estimates of various hypoglycaemic events are identical, and consistently reported in published and unpublished sources.
