Griffin 2000 Cambridge logistic risk of undetected type 2 diabetes

Griffin 2000 Cambridge logistic risk of undetected type 2 diabetes. p = 1/(1+e^(-λ)); λ = -6.322 - 0.879 if female + 1.222 antihypertensive + 2.191 steroids + 0.063×age + BMI band (<25 0; 25 to <27.5 0.699; 27.5 to <30 1.97; ≥30 2.518) + family (parent or sibling 0.728; parent and sibling 0.753) + smoking (former -0.218; current 0.855). Age 40-64. Probability 0-1. Not FINDRISC, not ADA, not a glucose assay, not a diagnosis.
