Abbreviations: CI, confidence interval; Avg., average; CE, cost-effectiveness

Note: Incremental change represents adjusted differences-in-differences estimate of pre-to-post change within and between control and intervention schools

^§As an example for interpretive purposes, each student, on average, ate 1.75 more fruits over the five week period. Achieving this goal, per student, cost $0.88 per fruit consumed.

^¶Vegetable outcomes were not included in economic e valuation because there was no statistically significant intervention effect.

^*Includes 5 schools only (2 intervention and 3 control schools); because of the high number of students who were eligible for the NSLP in 4 schools, LAUSD allowed all students to receive free meals at those schools. NSLP data were not collected for one intervention school.

^†Excludes one control school; one school’s store was closed due to structural damage.
