Baseline percent energy from fat	0.49	0.049	10.2	<0.0001
Change from baseline to DPP year 1	0.26	0.045	5.92	<0.0001
Number of HELP/BOOST participation	-0.063	0.021	-2.8	0.003

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 0.23.
