IGF1 and cancer: The probability of being classified as CP or PDAC for a particular patient is calculated with their values of CA 19–9, IGF-1 and albumin, using the following function, where β0, β1, β2, β3 and β4 are parameters estimated by the model:Prob(Pancreatic_cancer)=e(β0+β1CA19−9+β2IGF1+β3Albumin)1+e(β0+β1CA19−9+β2IGF1+β3Albumin)
