Unpaired t test of frequency of MSI-L or -H in CFC from donors in 2 age groups

	Age group, 0-45 y (n = 30)*		Age group, 46-84 y (n = 32)*		P†
	μf,‡ %	± SEM, %	μf,‡ %	± SEM, %
MSI-L	20.4	± 2.7	25.3	± 2.4	.0894
MSI-H	4.2	± 1.0	12.9	± 2.9	.0064*

^*n is the number of donors in each group.

^†P value was calculated by comparison between the 2 age groups (0-45 and 46-84 y). Asterisk after a value denotes significance.

^‡μf is the average relative frequency of MSI-H or MSI-L CFC from all donors within each age group.
