Prognostic value of glycaemic variability for mortality in critically ill atrial fibrillation patients and mortality prediction model using machine learning

HIGHLIGHTS

• What: The aim of this study was to assess the relationship between GV and short-, intermediate-, and long-term all-cause mortality in patients with AF in the ICU. In this analysis, blood glucose samples were collected exclusively during the ICU stay, ensuring that GV reflected the fluctuations in blood glucose levels specifically during the critical period of ICU. In this study, GV was calculated based on the formula GV=standard deviation of blood glucose / mean blood glucose × 100%.[23]. The raw data extracted for this study had varying proportions of missing values (Supplementary Table S1), serum . . .
