Figure 2.

Logistic curves showing the predicted and observed probability of undiagnosed diabetes at different levels of POC capillary glucose (A), Mohan's diabetes risk score (B), and Ramachandran's diabetes risk score (C). For each figure panel, the curve is for the predicted probability and the shaded area is for the 95% CI. The black circles are for the observed probability (1.00 for those with undiagnosed diabetes and 0.00 for those without diabetes). Solid horizontal and vertical lines are added at regular intervals to assist interpretation. Vertical broken lines are also displayed at the cutoff points of capillary glucose and risk (5.6, 6.1, and 7 mmol/l), Mohan's score (60), and Ramachandran's score (21) used to define high risk of undiagnosed diabetes.
