Accuracy of the Dementia Screening Index (DSI) and MHAS Late Life Risk Index

	MHAS (95% CI)	DSI (95% CI)
Area under the curve	0.74 (0.70–0.77)	0.72 (0.69–0.76)
Sensitivity	0.69 (0.64–0.70)	0.57 (0.50–0.63)
Specificity	0.67 (0.66–0.69)	0.78 (0.76–0.79)
Positive predictive value	0.16 (0.14–0.18)	0.19 (0.16–0.22)
Negative predictive value	0.96 (0.95–0.97)	0.95 (0.94–0.96)
Accuracy	68%	76%

The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated according to an optimal cut-off score of 16 points for the MHAS late life risk index and 23 points for the DSI.
