    High glycemic variability (GV) is significantly associated with increased short-term mortality in hospitalized COVID-19 patients.

  • 2

    The meta-analysis included 10 cohort studies with 77,395 patients, revealing 8,189 deaths linked to high GV.

  • 3

    The risk ratio for mortality associated with high GV was 2.10, indicating more than double the risk compared to low GV.

  • 4

    Older patients (mean age ≥ 62 years) showed a stronger association between high GV and mortality (RR = 2.79) than younger patients.

  • 5

    The findings support the potential of GV as a prognostic marker for short-term mortality in COVID-19 hospitalized patients.
