The 1-hour post-load glucose level is more effective than HbA1c for screening dysglycemia

To assess the performance of HbA1c and the 1-h plasma glucose (PG ≥ 155 mg/dl; 8.6 mmol/l) in identifying dysglycemia based on the oral glucose tolerance test (OGTT) from a real-world clinical care setting. This was a diagnostic test accuracy study. For this analysis, we tested the HbA1c diagnostic criteria advocated by the American Diabetes Association (ADA 5.7–6.4 %) and International Expert Committee (IEC 6.0–6.4 %) against conventional OGTT...
