Allowed range: 25–90 years
Age in years. Each year adds 0.063 to the logit.
Allowed range: 15–60 kg/m²
Below 25 kg/m² is 0, 25 to below 27.5 is 0.699, 27.5 to below 30 is 1.97, and 30 kg/m² or higher is 2.518.

DOI: 10.1002/1520-7560(200005/06)16:3<164::AID-DMRR103>3.0.CO;2-R. PMID: 10867715. The logistic coefficients are printed in the appendix of Park PJ, Griffin SJ, Sargeant L, Wareham NJ. The performance of a risk score in predicting undiagnosed hyperglycemia. Diabetes Care. DOI: 10.2337/diacare.25.6.984. PMID: 12032103. Probability = 1 / (1 + exp(-(alpha + sum beta x))), with alpha = -6.322. Female is -0.879 and male is 0. Prescribed antihypertensive medication is 1.222. Prescribed steroids are 2.191. Age adds 0.063 per year. Body mass index below 25 kg/m² is 0, 25 up to but not including 27.5 is 0.699, 27.5 up to but not including 30 is 1.97, and 30 or higher is 2.518. No first-degree relative with diabetes is 0, a parent or a sibling is 0.728, and both a parent and a sibling is 0.753. Never smoking is 0, ex-smoking is -0.218, and current smoking is 0.855. The result is that probability in percent. The papers do not print probability categories. (2000)
