Table 3 AUC comparisons between the cross-validated risk scoresa and the FCSRT crude scores for the prediction of dementia and Alzheimer's disease at 3 and 5 years in the Montpellier center (testing dataset)

From: Predicting dementia using socio-demographic characteristics and the Free and Cued Selective Reminding Test in the general population
