Estimated Medical Expenditure by Intervention

	Average Monthly Costs
	Intervention	Matched Comparison	Gross Difference	P	Net Difference
Medically Tailored Meals	$843	$1413	−$570	***	−$220
Non-Tailored Food	$1007	$1163	−$156	**	−$10

Estimates from gamma regression models adjusted for: Received Medically Tailored Meal, Index Year, Total costs in 12 months prior to intervention, Risk Score, Comorbidity Index, CCA Enrollment Year, Insurance Product, Age, Age squared. Percent of ZCTA that is rural, Percent households in ZCTA living in poverty, Non-Hispanic White, Non-Hispanic Black, Hispanic, Female, prescription of medication classes prior to intervention (Insulin, Anti – hypertensive, Other CVD medication, Anticoagulant, Proton Pump Inhibitor, Anti-retroviral, Percent of Medicare beneficiaries in ZIP code that had PCP visit in last 12 months, English primary language, Phosphate binder, Inhaler, Oral steroids, and Antibiotics), and follow-up time

Abbreviations: CCA—Commonwealth Care Alliance; ZCTA—ZIP Code Tabulation Area; CVD—Cardiovascular Disease; PCP—Primary Care Provider

Gross Difference represents estimated difference in healthcare claims by intervention status. Net difference represents estimated difference in healthcare expenditures, accounting for the cost of the intervention

P value tests the null hypothesis that the difference in gross costs between intervention and matched controls is equal to zero
