Table 4.

Time ratios for dementia conversion among people with MCI, with 95 % confidence intervals (CI), controlling for age, education, gender and APOE-4 alleles. Ratios greater than one indicate a longer survival time.

ADAS-Modified	0.66 (0.58, 0.76)	0.69 (0.61, 0.77)
ADAS-Rasch	0.73 (0.65, 0.83)	0.80 (0.73, 0.88)
ADAS-Tree	0.64 (0.56, 0.74)	0.67 (0.59, 0.76)
