3-year risk of type 2 diabetes by glucose, age, sex, and Scottish Index of Multiple Deprivation (SIMD) score: coefficients and odds ratios from logistic regression models.

There were no statistically significant interactions (on the scale of the linear predictor) for any of these variables. The natural logarithm of glucose in mmol/l was used for all models. Glucose provided in mg/dl should be converted to mmol/l by dividing by 18. The 3-year risk of type 2 diabetes is the inverse logit of the linear predictor (sum of the relevant coefficients). For example, for a male patient aged 60 with a glucose of 5 mmol/l the risk of type 2 diabetes is calculated as follows:Fitted values with standard errors and the model variance/covariance matrix are shown in Tables S8 and S9. We have also provided an online tool to carry out this calculation, which is available at www.cphs.mvm.ed.ac.uk/diabetes-risk/.
