Table 4 Comparison of models assessing the predictive validity for the onset of dementia of consistent, reverter, and uncertain MCI diagnoses based on Conventional (Model 1), Neuropsychological (Model 2) criteria, and combined model (Model 3).

From: Conventional and neuropsychological criteria for mild cognitive impairment show similar prognostic value for dementia across 12 years in a non-clinical setting
