Outcome = prediction of progression to all-cause dementia; Reasonable fit by the Hosmer and Lemes how Test for all models; 1 degree of freedom for each model variable.
* - exponentiation of the B coefficient, which is an odds ratio in the settings of this type of model
DRS-2: Dementia Rating Scale-2; SR: Sentence Repetition.
