Table 7.

Participant demographics of three datasets (AIBL, ADNI, MACC) used for MCI progression prediction before and after matching age and sex. After matching, the paired t-test p value between the age of the two groups (sMCI and pMCI) was 0.87. For sex, p value for chi-square goodness of fit test between the two groups was 0.99.

		Participants	Age (mean years ± SD)	Sex (female)
Before matching	sMCI	483 (AIBL: 13, ADNI 391, MACC: 79)	73.0 ± 7.38	42%
	pMCI	323 (AIBL: 10, ADNI 274, MACC: 39)	74.2 ± 6.83	45%
After matching	sMCI	288 (AIBL 10, ADNI 239, MACC 39)	73.9 ± 6.93	45%
	pMCI	288 (AIBL 10, ADNI 239, MACC 39)	74.0 ± 6.87	44%
