Overlap of abnormal carbohydrate metabolism by OGTT criteria and A1C test criteria alone or in combination with fasting glucose criteria. A: OGTT criteria and A1C test criteria (the κ coefficient was 0.070, P = 0.200). B: OGTT and fasting glucose criteria (the κ coefficient was 0.841, P = 0.000). C: OGTT and the combination of A1C test and fasting glucose criteria (the κ coefficient was 0.669, P = 0.000). D: Women classified as having IFG vs. women classified as having IGT (the κ coefficient was 0.141, P = 0.017).
