Mean amplitude of glycemic excursion and mortality in critically ill patients: A retrospective analysis using the MIMIC-IV database

CONCLUSION: MAGE exhibits effective predictive value for mortality in ICU patients, with distinct thresholds for diabetic and non-diabetic populations. These findings underscore the importance of tailored GV management strategies in critical care settings and support the adoption of MAGE as a standardised metric for GV assessment in ICU settings.
