CGM Versus OGTT in Early-Stage Type 1 Diabetes: Comparative Predictive Accuracy and Clinical Implications

CGM Versus OGTT in Early-Stage Type 1 Diabetes: Comparative Predictive Accuracy and Clinical Implications

This review synthesizes evidence demonstrating that continuous glucose monitoring (CGM) metrics, particularly time above 140 mg/dL, predict progression to stage 3 type 1 diabetes with accuracy comparable to oral glucose tolerance test (OGTT), offering a practical tool for early disease monitoring.

OGTT-Derived Surrogate Indexes Outperform Fasting Measures in Predicting Type 2 Diabetes Risk: A Longitudinal Analysis

A longitudinal study of 2,260 participants confirms that oral glucose tolerance test (OGTT)-based surrogate indexes, particularly Gutt and Cederholm, are superior to fasting-only measures in predicting type 2 diabetes, providing high clinical utility for metabolic risk stratification.
