The regression β-coefficient values of the predictor variables in the multiple logistic regression model were rounded off to the nearest integer (age ≤ 39 years at presentation with first MEN1-related primary manifestation = 1.05, recurrent PHPT = 2.10, diagnosis of dpNET = 1.44, and diagnosis of collagenoma or angiofibroma = 0.86). Here, MEN1 is linked to Angiofibroma.
