Exploring the impact of different definitions of level 1 and level 2 sensor‐detected hypoglycaemia upon frequency of hypoglycaemia and time below range: The Hypo‐ METRICS study

<p dir="ltr">Continuous glucose monitoring (CGM) systems are now standard of care for people with insulin-treated diabetes, with time below range (TBR) and frequency of sensor-detected hypoglycaemia (SDH) accepted metrics quantifying hypoglycaemic exposure and risk, in research outcomes and for clinical purposes.<a href="https://dom-pubs.pericles-prod.literatumonline.com/doi/10.1111/dom.70238#dom70238-bib-0001" target="_blank">¹</a> Whilst much interest is focused on TBR as a cumulative summary of hypoglycaemia exposure, recent work has highlighted the impact of the frequency of hypoglycaemic episodes, with up to 65% being asymptomatic whilst many symptomatic ones are not associated with a low sensor value.
