Postmeal (2.0 h)	2.33 ± 0.08	2.30 ± 0.09	0.646
Augmentation index
Premeal (−0.5 h)	22.5 ± 2.3	23.8 ± 2.7	0.705
Postmeal (2.0 h)	12.4 ± 2.2	13.2 ± 2.4	0.794
Subjects with endothelial dysfunction (n = 14)
Reactive hyperemia index
Premeal (−0.5 h)	2.32 ± 0.19	1.50 ± 0.04	0.002
Postmeal (2.0 h)	2.34 ± 0.19	2.27 ± 0.29	0.383
Augmentation index
Premeal (−0.5 h)	26.1 ± 5.7	23.6 ± 5.5	0.752
Postmeal (2.0 h)	14.8 ± 5.3	12.5 ± 3.9	0.714

Notes:

^aP-values were calculated from a repeated measures analysis of variance model between dairy and nondairy treatments.

Abbreviations: h, hour; SEM, standard error of the mean.
