Table 4:

Brain FLAIR discrete hyperintense foci associated with age

	Correlation with Age
	r_s	P
1.5T discrete foci: total cerebral number	0.69	0.005
1.5T discrete foci: total cerebral volume	0.70	0.006
3T discrete foci: total cerebral number	0.74	0.0001
3T discrete foci: total cerebral volume	0.72	0.0002

Note:—r_s = Spearman correlation coefficient. According to Choi's test for correlations, there was no difference in the correlation between age and number of hyperintense foci (p = 0.2) or age and hyperintense foci volume (p = 0.3) when comparing the 2 scanners. See also Fig 3.
