Table 2. Final regression model of predictors of total daily energy intake (kcal/day) at year 9 post-randomization.

	Estimate	Standard Error	t-value	Pr> |t|
Intercept	630.5	156.2	4.04	<0.0001
Age at Randomization (years)	1.2	2.2	0.56	0.58
Female	-83.6	48.5	-1.72	0.086
African American	-38.6	57.1	-0.68	0.50
Hispanic	-57.4	63.2	-0.91	0.36
American Indian	21.6	96.7	0.22	0.82
Asian American or Pacific Islander	-206.8	92.6	-2.23	0.026
Diabetes duration (years)	0.54	6.90	0.08	0.94
Baseline total energy intake (kcal/day)	0.59	0.032	18.6	<0.0001
Caloric change from baseline to DPP year 1 (kcal/day)	0.31	0.037	8.4	<0.0001

Age, sex, race/ethnicity and diabetes duration (0 for non-diabetic) are forced to stay in the model, regardless of significance. White is the reference group for race/ethnicity. Model R² is 0.40.
