Analysis of Fasting Plasma Glucose Values for Optimal Detection of Abnormal Responses on the Oral Glucose Tolerance Test in at-Risk Study Subjects

Objective To identify the fasting plasma glucose (FPG) value with the best performance for detecting an abnormal response on the oral glucose tolerance test (OGTT) in patients at risk for having type 2 diabetes. Methods All patients who underwent a 2-hour OGTT during an 18-month period were included in this study. Pretest and posttest odds, likelihood ratios, and receiver operating characteristic curves were used to identify the FPG value most...
