Results of regression coefficients (SE) from repeated-measures regression analyses to examine the association between each of the standardized Dietary Guidelines for Americans Adherence Index (DGAI) and weighted DGAI (wDGAI) values and changes in minimal diameters of coronary arteries in the postmenopausal women with established coronary artery atherosclerosis enrolled in the Estrogen Replacement and Atherosclerosis Trial (n = 224)

	Original DGAI		wDGAI
	β (SE)1	P	β (SE)1	P
Crude	−0.002 (0.013)	0.897	−0.029 (0.015)	0.059
Multivariate model 12	−0.007 (0.014)	0.636	−0.045 (0.017)	0.010
Multivariate model 23	−0.011 (0.014)	0.441	−0.049 (0.017)	0.004

¹SEs of the coefficients for wDGAI and DGAI were estimated by 2-stage (nested) bootstrap analyses.

²Multivariate model 1 included age categories (<60, 60–64.9, 65–69.9, or ≥70 y), study site (3 levels), education status (3 levels), frequency of walking (days per week, continuous), cigarette smoking status (yes or no), energy intake (quartiles).

³Multivariate model 2 included the variables in model 1 plus systolic blood pressure (continuous), casual glucose concentration (continuous), self-report of cholesterol-lowering drug use (yes or no), and self-report of chest pain (yes or no).
