Multinomial Logistic Regression Analyses for Associations between Low Dietary Approaches to Stop Hypertension (DASH) ^£ Accordance (Compared to Higher Accordance) and Rapid eGFR Decline^* (N = 1529)

Model	Variables Included	non-HTN N = 877 N events = 93	HTN N = 652 N events = 100	P interaction
		Risk Ratio (95% Confidence Interval)	Risk Ratio (95% Confidence Interval)	Between HTN and DASH accordance groups
1	Low versus Higher DASH Accordance	0.97 (0.66, 1.44)	1.80 (1.33, 2.44)	0.001
2	+ Age, Sex, Race	0.94 (0.61, 1.44)	1.80 (1.33, 2.45)	0.001
3	+ Poverty Status, Tobacco Use, Education level	0.87 (0.60, 1.25)	1.74 (1.22, 2.47)	0.001
4	+ Diabetes	0.87 (0.60, 1.26)	1.71 (1.19, 2.44)	0.001
5	+ Systolic BP	0.89 (0.61, 1.29)	1.68 (1.17, 2.42)	0.001
6	+ Total Energy Intake	0.83 (0.56, 1.24)	1.68 (1.17, 2.42)	0.001

Abbreviations: HTN, hypertension; BP, blood pressure.

^£Individuals meeting the DASH target for a nutrient received a score of 1 while those who achieved the intermediate target for a nutrient received a score of 0.5 for that nutrient, for a total possible accordance score of 9. Persons with accordance scores falling between 0–1.0 were defined as low DASH accordance, while those with higher DASH accordance had scores between 1.5 and 8.0.

^*Rapid eGFR decline defined as eGFR decrease > 3 mL/min per 1.73 m² per year during follow-up.
