Model | Odds Ratio (95% CI) | PValue | Undiagnosed Diabetes, No. (%) | AUC (95% CI)^{a} |
---|---|---|---|---|

AUC = area under the receiver operating characteristic curve; BMI = body mass index; CI = confidence interval. | ||||

Note: Only risk factors with P =.15 in Table 4 were included. | ||||

^{a} An AUC of 0.50 means that the model does not predict the outcome better (more accurately) or worse (less accurately) than random guess; an AUC greater than 0.50 means that the prediction is better than random, and an AUC less than 0.50 means that the prediction is worse than random. | ||||
