TABLE 2.

Differences in the number of VMS reported/measured via various modalities, for total sample and by race/ethnicity

	Total sample	White	African-American
	M(SD)	M(SD)	M(SD)
Daytime VMS (#)
End of day recalled – prospectively reported VMS b	−0.75 (2.88)	−0.24 (1.96)	−1.34 (3.61)
End of day recalled – physiologically measured VMSa	−3.22 (5.00)	−1.89 (4.37)	−4.79 (5.29)
Overnight VMS (#)
Morning recalled – prospectively reported VMS	0.16 (3.56)	0.20 (3.01)	0.10 (4.13)
Morning recalled – physiologically measured VMS	1.37 (2.72)	1.18 (2.21)	1.60 (3.22)

Differences by race/ethnicity:

^aP<0.05

^bP<0.10

Note: More negative indices represent fewer VMS (#) recalled than prospectively reported or physiologically measured; more positive represents more VMS (#) recalled than prospectively reported or physiologically-measured.
