Diagnostic Models for Identifying New Cases of Diabetes Mellitus in Patients with Moderate to Severe COVID-19: The Impact of TyG Index, Body Mass Index, and Inflammatory Biomarkers

1

Insulin resistance and obesity are significant risk factors for developing type 2 diabetes mellitus in COVID-19 patients.
2

The triglyceride-glucose index can enhance diagnostic accuracy for newly diagnosed diabetes when combined with BMI and inflammatory markers.
3

Elevated BMI is strongly associated with an increased risk of newly diagnosed diabetes in patients recovering from COVID-19.
4

Cardiometabolic monitoring is essential for COVID-19 survivors, especially those with obesity and insulin resistance risk factors.
5

Further validation of diabetes prediction models is necessary to effectively estimate risk in vulnerable populations post-COVID-19.
