CLAIM CARD
Mechanistically, hypoglycemia-induced mortality pathways involve autonomic activation, arrhythmogenesis, and prothrombotic states, providing a strong biological rationale for association. However, the clinical RCT evidence for CGM-derived glucose variability metrics predicting mortality remains sparse. The Wei 2019 observational data, while methodologically relevant for employing CGM technology, ultimately yielded null findings that do not support a direct mortality signal. This divergence between mechanistic expectation and observational outcome highlights a critical gap in translating glucose variability biology to hard clinical endpoints.
