Test characteristics of different cut-offs of glucose from the 75 g OGTT at 14–16 weeks for identifying LGA children. Sensitivity, specificity, PPV and NPV across the different GDM diagnostic criteria using 1% (fasting) and 4% (60 and 120 minutes) decreases from standard 30–32 week OGTT cut-offs. The % decrease in glucose is shown in italic. Vertical text shows the actual glucose values at the different time-points.
