Predictive criterion validity for each algorithmic classification of early cognitive impairment (ECI) at baseline predicting progression to consensus diagnosis of MCI/dementia during follow up.

Algorithmic classification of early cognitive impairment (predictor)	N*	Number of progressors	Person-years	Hazard ratio	95% CI	AIC	BIC
impairment in Card Rotation or CVLT immediate recall	1463	35	16453	3.53*	(1.59, 7.84)	421.12	447.56
impairment in 1+ memory or 3+ non-memory tests	1459	36	16270	2.24*	(1.11, 4.51)	444.06	470.48

Note. MCI=mild cognitive impairment. CVLT=California Verbal Learning Test. CI=confidence interval.

Participants who had diagnosis of MCI/dementia at baseline were removed from the analysis. The bolded values indicate statistically significant results (p<0.05).
